In the name of God, go!

Sir Ian Blair's position as head of the Metropolitan Police Force is now completely untenable.

As I have said before, he cannot remain as Britain's most senior policeman. Yesterday his force was found guilty of 19 "catastrophic" failures over the shooting of the innocent Brazilian Jean Charles de Menezes. The force was fined £175,000.

PM Gordon Brown and Home Secretary Jacqui Smith have both given Blair their backing - for now. The mayor Ken Livingstone has also said, "The idea that people farther up the food chain somehow bear... responsibility is nonsense."

It is not nonsense at all. The ultimate responsibility for any organisation always always rests with the head. If a building falls down, the architect is responsible not the brickie who worked on the site.

Why is it that this government and its acolytes can never take responsibility? Why is it always time to draw a line and move on?

The sooner Ian Blair is removed from his post and replaced with a policeman who sees his job as nicking villains and not being obsessed with diversity the better.

Ian Blair - In the name of God, go!

One Blair has gone - now it's high time for a second to leave his job.

The Independent Police Complaints Commission report into the shooting of Jean Charles de Menezes says that Metropolitan Police Force commissioner Sir Ian Blair was "almost totally uninformed" about what happened at Stockwell tube station.

This is simply unbelievable - either Blair knew what happened and lied about it - for which he should resign - or he didn't know in which case he is incompetent and should be sacked.

The report lays the blame squarely on Assistant Commissioner Andy Hayman. It says that he "misled" senior officers by failing to tell them the dead man was not one of four wanted suicide bombers.

If Blair did not know, he should have done. He should have asked questions of his senior men; he should have made it his business to find out before making any public statements.

The buck stops at the top and the top, for now, is Sir Ian Blair.

Show some backbone, man, and do the honourable thing. Your time as head of the Met is as already tarnished as that of the man whose surname you shared was at No 10.

In the name of God - go!

Is Ian Blair fit for purpose?

One some times has to wonder about the fitness of Sir Ian Blair to be commissioner of the Metropolitan Police Force.

On the Jean Charles de Menezes tragedy, he stated that he was unaware that an innocent man had been murdered until the next day. Why? With ultimate responsibility for the force, he should have known.

Blair either did know in which case he is a liar, or he really didn't know and he is incompetent.

Now we learn that he attended a dinner at which a fellow guest was Lord Levy, currently under investigation in the cash for honours row by the Metropolitan Police Force. Blair knew that Michael Levy was going to be present (he asked not to be seated near the peer or his wife), so what on earth prompted him to attend?
