Only one of today's Party Leaders voted in favour of the war in Iraq.
As did almost all of his party's MPs, including the leading candidate to succeed him.
Another of those candidates was a fanatical media cheerleader for that war.
The utterly vindicated Jeremy Corbyn said all that he could have said.
Although he has since spoken outside Parliament to apologise for the war on his party's behalf, it really would not have done for a politician to have stood up in Parliament and demanded a criminal trial.
Over, then, to the appropriate authorities in such matters.
