Yes Gordon Brown, once again bottling out. He's used some committee at the House of Commons as an excuse for not attending, when committees are rescheduled all the time. He just doesn't have the bottle to be seen signing such an important document when he won't honour Labour's election pledge to hold a referendum on it. The argument that the "Treaty" is too different from the Constitution just doesn't wash.
If Brown wants to be taken seriously, he's got to learn that a Prime Minister can't simply hide every time there's something controversial, the way he often did when he was Chancellor. And if he wants the county to adopt the "Treaty" he should be willing to sign it in public. Even Tony Blair had more courage than this.
Or did he just skip the ceremony so he could avoid running into Peter Mandelson?
