A couple of weeks ago, the Sunday Mirror ran an article claiming that Bush and Blair were arguing. The Mirror is a tabloid and not exactly trustworthy; however, there were elements of the story which might prove true later on:
Presidential advisers in Washington wanted Mr Bush to be the sole leader to make a Christmas visit to troops in Baghdad and urged Downing Street to postpone any visit.
The US refused to co-operate on security arrangements for a Christmas visit by Mr Blair, who is going to spend the festive season with his family in the Egyptian resort of Sharm al-Sheikh.
As it turns out, Blair just visited Iraq. Not, mind you, over Christmas, but very close — which fits the Mirror story, since Bush didn’t want him visiting over Christmas itself.
