Former Prime Minister Sir John Major has said the decision to withhold some of the correspondence about the Iraq war will be "very embarrassing" for Tony Blair.
Sir John Major told Radio 4's Today programme: “I think it is a pity the papers are going to be withheld for several reasons. Firstly, they will leave suspicions unresolved and those suspicions will fester and maybe worsen."
He also argued that the ruling ran counter to Mr Blair's actions to make government more transparent.
"And secondly, in many ways I think withholding them is going to be very embarrassing for Mr Blair, not least of course because he brought in the Freedom of Information Act into law when he was in government."
Former Prime Minister Sir John Major has paid tribute to BBC broadcaster John Cole, saying that when he "spoke, everyone listened."
Sir John Major said he was "too sensitive" over press coverage towards him when he was Prime Minister, as he gave evidence at the Leveson Inquiry.
The former Prime Minister - who held office from 1990 to 1997 - said his poor relationship with the press was down to his decision not to court them which, he added, would have been "undignified".
Sir John added that the press cannot hold the Government to account if there is too much "chumminess" between them.
Sir John Major has been speaking to ITV about serving as one of the Queen's 12 Prime Ministers. He is also patron of the Diamond Jubilee Trust.
He will be among those attending the Thanksgiving Service at St Paul's Cathedral later this morning.
