The Sun and Mirror led the political news agenda this week with scoops about Tony Blair's expected departure.
The Mirror published a leaked memo on Tuesday which revealed plans for a farewell tour for the Prime Minister which would promote the "triumph of Blairism".
Then The Sun claimed on Wednesday that Blair would leave office on 31 May — a story which was widely followed up on the front pages of rival papers' late editions.

Kevin Maguire said: "Tuesday's Mirror exclusive was undoubtedly the catalyst for the dramatic Westminster scenes which have been unfolding ever since."
The Daily Mail pulled off a coup in its first week of "live" publishing in Australia by breaking the news of Tony Blair's believed departure date.
It meant that Australians could read the news on Wednesday at 11am in the morning (2am in the UK), before most Daily Mail readers had got their copies.
The Daily Mail and Mail on Sunday claim to be the first British national newspapers to publish "live" in Australia and New Zealand. The titles are available at newsstands in Sydney, Canberra and Auckland within minutes of them rolling off the presses in the UK. The Mail is aiming to pick up readers among the 1.5 million British expats living down under.
