A cross-party group of MPs, including former SNP leader Alex Salmond, may renew their attempts to impeach Tony Blair following the publication of the Chilcot report later this year.
According to reports, Mr Salmond has begun rallying support for an attempted prosecution, pending the findings of the report, which will be released in July.
In the UK, impeachment is the procedure whereby MPs can vote to have someone put on trial before the House of Lords. It is a centuries-old procedure which has not actually been used since 1806.
While some MPs still want to use the procedure to hold Mr Blair to account over his actions in the run-up to the Iraq War, Mr Salmond told The Times the best route to a prosecution could lie through the International Criminal Court (ICC).
A campaign to impeach the former Prime Minister was first launched in 2004, backed by a cross-party group of MPs that included Boris Johnson – now the figurehead of the EU referendum Leave campaign and a favourite to become Prime Minister in the event of Brexit.
Conservative MP Sir David Amess told The Times he had been contacted by Mr Salmond seeking support for a new campaign, pending the findings of the Chilcot report.
“If it’s proved that Tony Blair misled everyone, I personally am determined to see justice prevail and to see him impeached,” Sir David said.
