A federal grand jury in the US state of Virginia has indicted former FBI Director James Comey on two charges related to his testimony to Congress.

Mr Comey, who has long drawn US President Donald Trump’s criticism, is accused of lying to Congress during his September 2020 testimony over whether he authorised the leak of classified information to the media.

Responding to the indictment, Mr Comey declared himself innocent and said he had “great confidence in the federal judicial system”.

The indictment comes days after Trump called on the country’s top law enforcement official, Attorney General Pam Bondi, to more aggressively investigate his political adversaries, including Mr Comey.

The probe is being led by Lindsey Halligan, the US Attorney for the Eastern District of Virginia, who was previously Trump’s personal lawyer and took over her new role on Monday.

Mr Comey’s arraignment – where charges are formally read out in front of a defendant in court – has been set for the morning of 9 October in Alexandria, Virginia at 10:00 local time (14:00 GMT), the BBC’s US partner CBS reports.

Bondi said in a statement that the indictment “reflects this Department of Justice’s commitment to holding those who abuse positions of power accountable for misleading the American people”.

Mr Comey has been charged with one count of making false statements and another of obstruction of justice.

The alleged false statements relate to telling a senator on the Senate Judiciary Committee that he had not “authorized someone else at the FBI to be an anonymous source in news reports” regarding an FBI investigation, presumed to be the inquiry into whether Russia meddled with the 2016 election.

The second count of obstruction alleges that Mr Comey “did corruptly endeavor to influence, obstruct and impede the due and proper exercise of the power of inquiry under which an investigation was being had before the Senate Judiciary Committee by making false and misleading statements” before that committee.

The Justice Department asked the grand jury to consider three charges against Mr Comey, but it could only agree that two of them were backed by enough evidence to be tried in court.

The third count was another charge of making false statements.

A grand jury is a group of citizens set up by a prosecutor to determine whether there is enough evidence for charges to be filed. In legal terms, it determines whether probable cause exists to believe a crime has been committed.

Mr Comey is the first ex-FBI director to be indicted for a crime, and he maintains that he has not lied under oath.

If found guilty, he could face up to five years in prison.

A lawyer for Mr Comey, Patrick Fitzgerald, issued a short staying saying his client denied the charges, adding: “We look forward to vindicating him in the courtroom.”

Mr Comey said in a separate video statement: “My family and I have known for years that there are costs to standing up to Donald Trump.”

“We will not live on our knees, and you shouldn’t either,” he continued, adding: “And, I am innocent. So, let’s have a trial.”

The charges were filed shortly before the five-year statute of limitations was set to expire on Tuesday.

The case had recently been handed over to a new prosecutor after Erik Seibert, the original US attorney overseeing the case, was fired by the Trump administration. He was replaced by Ms Halligan.

According to charging documents, Mr Comey “did willfully and knowingly make a materially false, fictitious, and fraudulent statement… by falsely stating to a US Senator” that he had not “authorised someone else at the FBI to be an anonymous source in news reports”.

Prosecutors say the statement was false, as Mr Comey had directed an unnamed person “to serve as an anonymous source in news reports regarding an FBI investigation concerning” another unnamed person.

Around 30 September 2020, the document states, Mr Comey “did corruptly endeavor to influence, obstruct and impede the due and proper exercise of the power of the inquiry” of the US Senate Judiciary Committee through “false and misleading statements”.

The case is considered to be the highest-profile indictments of a public figure during Trump’s second term.

Trump recently voiced his frustration that prosecutions of his public critics such as Mr Comey, Senator Adam Schiff and New York Attorney General Leticia James are taking so long.

“We can’t delay any longer, it’s killing our reputation and credibility. They impeached me twice, and indicted me (5 times!), OVER NOTHING. JUSTICE MUST BE SERVED, NOW!!!” Trump said on Truth Social last week.

After charges were filed, Trump called Mr Comey “one of the worst human beings this Country has ever been exposed to”.

“He has been so bad for our Country, for so long, and is now at the beginning of being held responsible for his crimes against our Nation. MAKE AMERICA GREAT AGAIN!”

Asked about Mr Comey hours before the indictment was unsealed, Trump called him a “bad person” but said he had no advanced knowledge of his prosecution.

Laurie Levenson, a former federal prosecutor and a law professor at Loyola Marymount University, said it will be a very challenging case to prosecute.

“It’s often the defendant’s word against someone else’s and you’re gonna have to look at the credibility of both,” she tells BBC News.

“And even if James Comey got things wrong, that doesn’t mean that he knowingly or intentionally lied to Congress. So proving that is going to be the heart of the case.”

Ms Levenson also said this prosecution and Trump’s public pressure to move forward on it suggests that the traditional firewall between the White House and the US Department of Justice had “collapsed with this case”.

Several Democrats condemned the charges, with House Democratic Leader Hakeem Jeffries denouncing them as “a disgraceful attack on the rule of law”, and vowing “accountability” for “anyone complicit in this malignant corruption”.

Mr Comey served as the FBI’s director between 2013 and 2017.

He had a tumultuous tenure that included overseeing the high-profile inquiry into Democratic candidate Hillary Clinton’s email just weeks before the 2016 election, which she lost to Trump.

He was fired by Trump amid an investigation into Russian interference in the 2016 election.

This is not the first investigation into the former FBI boss to be launched this year.

He was investigated by the Secret Service after he shared and then deleted a social media post of seashells spelled the numbers “8647”, which Republicans alleged was an incitement to violence against US President Donald Trump.

The number 86 is a slang term whose definitions include “to reject” or “to get rid of”, according to the Merriam-Webster dictionary, which also notes that it has more recently been used as a term meaning “to kill”, while Trump is the 47th US president.

In July, Mr Comey’s daughter Maurene Comey was fired from her role as a federal prosecutor in the Southern District of New York. She was given no reason for being removed from the office where she had worked for 10 years, according to media reports.

Earlier this month, she sued the Trump administration over her dismissal.

The Justice Department has been firing lawyers who worked on cases that angered the president, including a special prosecutor investigation of Trump.

Handheld scanners will be used to search children suspected of having a weapon in Cardiff schools under new guidance.

The guidelines, which are thought to be the first of their kind in Wales, deal with what happens when a child is thought to be carrying a weapon, and the next steps if one is found.

Cardiff council said it had been designed after calls by head teachers for up-to-date advice to keep students and staff safe, following growing concerns about knife crime in schools.

Sarah Merry, the council’s cabinet member for education, said while she understood parents “may feel anxious about the idea of searches”, they would not be part of a daily school routine or “done lightly”.

In 2013, the Welsh government introduced a power which allowed schools in Wales to screen pupils for a knife or other weapons, and to search pupils suspected of carrying a weapon.

New guidance sent to parents in Cardiff states a search may be necessary if staff have a “reasonable” suspicion that a young person has a weapon in school.

During a search, it added two members of staff would be present, and that in most cases a “search wand” would be used to remove any physical contact.

“Parents or carers will be informed following a search and the reasons for the search will be explained,” the guidance adds, with the purpose of the search also explained to the student.

Under the guidelines, if a weapon is found then an incident review meeting should be arranged within five school days of the incident with “at least one daily welfare check”.

The young person should not be allowed to go to school until this meeting has taken place, while a “trauma-informed investigation” would then take place to understand why the young people brought the weapon into school and the next steps that should be taken.

According to Cardiff council, the guidelines recognise “there are often complex reasons why a young person might carry a weapon” and encourages schools to work with families and other services so support can be put in place.

The guidelines have been rolled out to all primary, secondary and special schools after being developed through consultation with children, and co-produced with partners including South Wales Police, youth services and violence prevention experts.

Merry, who is also council deputy leader, said: “Head teachers have been asking for revised support in this area and it’s absolutely right that we’ve worked closely with them to create something practical and useful.

“It is also part of our review following incidents in other parts of the country and gives schools the tools they need to keep everyone safe – it’s not about creating fear; it’s about building confidence.”

As well as guidance on weapons, each school in Cardiff has appointed a violence prevention lead, who are senior staff members that will take part in specialist training to prepare them for real-life situations involving weapons or threats to safety.

Other actions taken to keep schools safe include lockdown rehearsals to help schools prepare for emergencies, and using the curriculum to “build a culture of respect and safety”.
