Labour leader Jeremy Corbyn has said he will likely support plans to hold Tony Blair in contempt of Parliament over Iraq.
Mr Corbyn said that he had yet to see the text of the motion.
But he added that he would "probably" back it.

MPs, including former First Minister Alex Salmond, want to sanction Mr Blair in the wake of a damning report into the 2003 invasion.
The official Iraq inquiry concluded that the war was launched before all peaceful options had been exhausted.
Mr Blair also presented intelligence on Iraq's ability to create weapons of mass destruction (WMD) with an unwarranted certainty, the Chilcot report said.

Mr Salmond said that MPs had a duty to respond to the findings.
"'No parliament worth its salt tolerates being misled," he said.
The former SNP leader, who voted against the war, also said that MPs had to learn the lessons of Iraq and "to examine what it is being fed by the executive" or risk repeating the same mistakes.
Mr Corbyn told the BBC's Andrew Marr show: "Parliament must hold to account, including Tony Blair, those who took us into this particular war.
He added: "I haven’t seen it yet but I think I probably would [vote in favour of it]."

If passed Mr Blair could be called before Parliament for questioning.
The former Prime Minister, who led his party to three successive general election victories, could also be stripped of his membership of the Privy Council.
After the report's publication Mr Blair apologised for the intelligence failures and the lack of planning for a post-conflict Iraq,.

But he refused to say that he was sorry for the decision to invade.
And he said that the findings showed that he did not lie or mislead MPs.
Conservative backbencher David Davis plans to table the motion on Thursday.
He said that the Inquiry has not ruled on whether Mr Blair had "lied or not".
But, he said: " If you look just at the debate (on the war) alone, on five different grounds the House was misled,"
He said: "Everybody I talk to thinks that there has been, as it were, a trial. But there’s no verdict. And the House has to deliver a verdict.”
Meanwhile, Mr Blair's former deputy prime minister Lord Prescott said that he now believes the US-led invasion of Iraq was illegal.
He offered his "fullest apology" to the families of the military personnel who died.
The push now has the backing of MPs from six political parties.
Supporters said that they were hopeful that the motion would be selected by the Speaker John Bercow and that they would build support for the move this week, when MPs are due to spend two days debating the findings of the Iraq Report.
SNP MSP James Dornan has also lodged a motion in the Scottish Parliament calling for those implicated by the findings of the Chilcot report to hand back their honours.
He said that the report exposed a “devastating establishment failure”.
They include Lord Goldsmith, the former Attorney General, who was made a Life Peer in 1999. The legal process in the run up to the war was described as “far from satisfactory”.
