A Conservative MP has claimed calls for Scotland to break away from the United Kingdom are being driven "by the likes of Mel Gibson".
Giles Watling, MP for Clacton, told the House of Commons he had been "fortunate enough to work in all four corners of this great Union".
During a debate earlier today the SNP's Cabinet Office spokesman Brendan O'Hara hit out at new Prime Minister Rishi Sunak saying it was "an absolute disgrace" that he has not granted the Scottish Government permission to hold a referendum on independence.
Watling said there should a timeframe on when another vote can be held.
He added: "We have fought shoulder to shoulder for freedom and democracy all over the world, not least at Waterloo and the landing beaches of Normandy.
"Does he agree it would be foolish to let this great and successful union fall apart on a whim, with the aid of the likes of Mel Gibson et cetera? Should there not be a legislative timeframe, say 25 years, before another referendum can be held?"
Cabinet Office minister Brendan Clarke-Smith replied: "People across Scotland want both of their Governments to be working together and focusing their attention and resources on the issues that matter to them and not talking about yet another independence referendum."
Hollywood star Gibson starred in and directed the 1995 historical film epic Braveheart, retelling the story of William Wallace, a leader in the first war of Scottish independence in the late middle ages.
O'Hara also said the responsibility for the Union has become a "hot potato and something (to) be passed from department to department".
He added: "My suggestion would be to the new Secretary of State that he uses this new responsibility to encourage the Prime Minister to respect the mandate that the Scottish people gave last year when they elected the pro-independence majority government with a commitment to holding a referendum.
"And would he agree, as my honourable friend has said, that a Prime Minister who was rejected by his own party members, but who was subsequently put into office, unelected by the members behind him, for them to then deny the wishes of the Scottish people in a free and fair election is an absolute disgrace?"
Cabinet Office minister Brendan Clarke-Smith replied: "There is still the mandate in Scotland from the independence referendum, we are very firm on that. And we will continue to support that and prioritise for the Scottish people and not to play politics and navel-gazing at this point in time."
