PMQs turned into something of a chuckle-fest but the only person not laughing appeared to be one Edward Samuel Miliband.

Try as he might to pin down the Tory toff on how Dave's loadsamoney friends in the City were being allowed to avoid tax, the PM was able to dodge the Miliband barbs because he had been provided with some readymade gags courtesy of, er, the Labour frontbench past and present.

The parting shot of an aide to the Welsh Labour leader, Carwyn Jones, was to liken the chief comrade to one of the Chuckle Brothers. But to add insult to Labour injury, one of the Chucklers responded by quipping that he would never want to be called an Ed Miliband. (NB the Chuckle Bros didn't even complain when Messrs Paisley and McGuinness were compared to them.)

As Flashman rolled off how former Blairite Ministers had cast aspersions about the chief comrade's policies, he asked: "Is it any wonder that the Chuckle Brothers have lodged an official complaint and said they don't want to be compared to the two clowns opposite."

If that was not enough Ed Balls's unfortunate lapse of memory over the name of a Labour supporter from the world of business also helped Blue Dave dodge the tax dodge question.

He barked: "The day after his Shadow Chancellor was asked on the television could he think of one single business leader(who supported Labour), do you know what he said - he said: 'Bill somebody.' Bill somebody's not a person, bill somebody's Labour's policy!" The Tory berserkers went, yes, berserk with glee. The comrades slunk deeper into their seats as the Miliband hole got deeper and deeper.

Ed stiffened his back and kept on stoically about the hedge fund tax avoiders but daylight was fast beginning to disappear as the PM asked if one of Labour's biggest donors, who had avoided tax by making a gift to Labour in shares, had given the taxpayers their money back.

There then followed a slanging match over your party donor was a bigger tax exile than my party donor by which time Red Ed's hedge fund dodgers' point had dissipated into thin air.

Meantime during all the blue-red dinging and donging, the SNP contingent appeared to be in a state of transcendental nirvana with glazed smiles on their faces; the Ashdown poll numbers still singing in their heads.
