In the first televised debate between the three main London mayoral candidates, we learned that former police chief Brian Paddick would not accept a job in a rival’s administration.

Paddick, who needs a huge swing in support to have any chance of election, has said that as mayor he would personally chair the Metropolitan Police Authority, which oversees the capital’s police.

But the Liberal Democrat candidate’s reply was quite clear when asked on BBC’s Newsnight whether he would serve under a re-elected Mayor Ken Livingstone, if offered the chance of running London police policy.

“No, I would not,” Paddick told host Jeremy Paxman during Tuesday’s programme.

“When I left the police I promised myself that I would only take advice, I would not take orders any more.”

We also learned that Livingstone would vote for Paddick — if forced to choose between him and the Tory runner Boris Johnson.

Perhaps little surprise there, but Labour’s Livingstone was the only one to answer Paxman’s question — which of the other two candidates would they vote for if they couldn’t vote for themselves.

Johnson “couldn’t possibly comment”, while Paddick couldn’t decide, saying his rivals were “bad in different ways”.
