Several of the papers focus on Lord Bragg's claims that Prime Minister Tony Blair almost left Downing Street because of personal and family reasons. The Daily Mail calls the suggestions of "colossal family strain", which has nothing to do with the Blairs' marriage, a "bombshell disclosure".
The Daily Express talks of "Blair's secret agony" after Lord Bragg's ITV News interview.
The Guardian claims Lord Bragg caught Number 10 on the hop but other papers speculate it may be a sympathy ploy.
'Unique stresses'
The Daily Telegraph details the words of Cherie Blair, which is serialising her book on Downing Street spouses.
"Living in Number 10 is of course an enormous privilege but it can also impose unique stresses on families."
The Prime Minster's wife writes that "Time and again, in the interviews we did, there was a feeling that family life was sacrificed to the machine".
The Times says despite Tony Blair's wobble in the spring, he is determined to carry on in the face of pressures.
'Big graveyard'
The Guardian leads on the violence in Iraq and wonders whether the country is descending into civil war.
The paper has a picture of a pile of shoes in the street which had belonged to the victims of a bomb in Baghdad.
The Independent devotes its entire front page to the story, calling it Hell on Haifa Street and giving a graphic account of the devastation.
The Daily Mirror quotes an Iraqi teacher who says Iraq is not a country but a big graveyard.
Protester 'dumped'
The protest by a member of the group Fathers 4 Justice at Buckingham Palace on Monday continues to make headlines.
The Times says Prince Charles has demanded that the Army take over security at all royal residences.
The Sun says Jason Hatch, the man who scaled the Palace dressed as Batman, has been dumped by his girlfriend because she is fed up with his stunts.
The Mirror quotes partner Gemma Polson as saying his campaigning had left no time for their baby daughter.
