IT was a classic Godzilla versus King Kong moment when Westminster's two top politicians took the deeply serious issue of cleaning up Britain's banks and simply sought to use it to swing, lunge and take chunks out of each other.

As we sat with our 3D spectacles on, the Labour giant got to his feet to ask Blue Dave if he supported the recommendations of the Banking Commission to jail errant bankers and stop bad bonuses.

Now, the chief comrade was clearly expecting a highly evasive non-answer but like a shot, Flashman declared: "Yes. I do support those measures."

Godzilla's swipe had clearly missed its mark, so he tried again and urged the PM to use the Banking Bill to make those necessary changes.

Dave swiftly said he would.

The Labour giant looked confused by his enemy's compliance.

Gathering himself, Godzilla noticed Boy George whispering in Flashman's ear and took the opportunity to urge the PM not to take advice from the part-time Chancellor.

The Tory toff responded by insisting he would rather take his chum's advice than that of the Shadow Chancellor, who had delivered the biggest banking bust in history.

The heat was up. Godzilla was now snorting steam. "I'm not going to take lectures from the guy who was the adviser on Black Wednesday in 1992," he snapped. The comrades roared.

But the Tory giant responded with a long lunge, quoting ex-Labour minister Lord Myners who admitted the Labour government was "culpable" for not regulating the banks. The Cons hooted and bayed with delight.

But Godzilla was not done. This time he quoted from King Kong himself in 2008 when he said the problem of the previous decade was "too much regulation" of the banks. Labour MPs cheered as their giant declared: "There you have it."

The crimson tide rose and the PM reminded MPs what the chief comrade said in 2008 – "no more boom and bust". The Tory chorus again struck up.

In his parting shot, Godzilla insisted despite his tough talk that Dave was dragging his feet on banking reform. "While ordinary families are suffering, he is giving a massive tax cut to the bankers."

As Labour hoots reverberated around the chamber, King Kong slowly rose and accused Godzilla of "another display of extraordinary weakness".

The clash of the monsters had again produced a lot of heat but precious little light.
