Where Tony Blair and Jack Straw have been now Gordon Brown 'must' follow

Gordon Brown declared that he was happy to appear before the Chilcot Inquiry before the General Election and is still expected to do so, although I fully expect him to wriggle out of this commitment as he has done before with other promises...

However the BBC report that:

"Members of the public who want to watch Gordon Brown's much anticipated appearance before the Iraq inquiry will be able to enter a ballot.

There is still is no date fixed for the prime minister to give evidence to the panel, chaired by Sir John Chilcot.

But the inquiry team has confirmed that it will be early in March.

A similar ballot was held when Tony Blair, who was prime minister in the run up and aftermath to the war, was grilled by the committee last month. "

Whilst Tony Blair was smooth and controlled in his giving of evidence, albeit not always answering the question he had been asked and Jack Straw was controlled and convincing even as he contradicted the evidence of other witnesses, Gordon brown is likely to be less convincing. As no witnesses are under oath there is no prospect of getting the 'the truth, the whole truth and nothing but the truth' from Gordon Brown, just as with Tony Blair and Jack Straw, but Gordon Brown is just not as convincing as the others and prone to inopportune anger. This could be ahot ticket...
