At Prime Minister’s Questions, David Cameron called on Mr. Brown to declare the Lisbon Treaty dead in the light of its rejection by Irish voters.

He said Brown must listen to the Irish people, asking, “What part of ‘no’ doesn’t he understand?”

It would be “arrogant and high-handed”, he told the Prime Minister, to try to force the Irish to hold a second referendum, especially as the British people have not even had one.

And he urged Mr. Brown to finally pluck up the “courage” to kill off the “half-dead” constitution, saying:

“I have seen more spine and leadership from a bunch of jellyfish.”
