SIR Sean Connery has warned David Cameron , Ed Miliband and Nick Clegg their parties will be decimated in Scotland unless they "deliver big" on more devolution to the Scottish parliament.

The actor, who lives in the Bahamas, said the SNP would "trounce" them in next year's General Election unless they agree to hand Holyrood full responsibility for raising what it spends.

Connery said: "I was ­disappointed that Scotland didn't vote Yes but the energy and resilience shown by people after the vote has been fantastic.

"Cameron and the other Westminster leaders made big promises to Scotland to get the No vote, and they are going to have to deliver big. Otherwise the SNP will trounce them in the next election.

"The sensible solution is for Scotland to be in charge of all its tax and spending. That way no-one could complain about who funds who."
