Jeremy Corbyn has clashed with the SNP after posting a video claiming the party helped usher in Margaret Thatcher’s government.
The Labour leader posted the 47-second video on Twitter looking back at the 1979 no-confidence vote which brought down James Callaghan’s government.
A total of 11 SNP MPs voted with the Conservative Party to force the general election that led to Mrs Thatcher entering Downing Street.
Mr Corbyn shared the video, captioned: "Forty years ago today, @theSNP did this..."
SNP leader Nicola Sturgeon responded: "Dear @jeremycorbyn - instead of talking about things that happened when I was eight years old, how about showing some leadership today?
"You could start by asking yourself why the polls show you still trailing behind the most incompetent Tory government in our lifetimes."
Stewart McDonald, the SNP MP for Glasgow South, added: "How about you get off you’re a*se and deal with the problems we face right now rather than indulging yourself in more fantasy bogeyman trash?"
The vote on no confidence followed the industrial unrest known as the Winter of Discontent and the referendum on the Scotland Act for greater devolution which, despite winning a majority, was not passed due to turnout not reaching the 40% threshold.
In the debate about the vote, Mr Callaghan said: "Tonight, the Conservative Party, which wants the act repealed and opposes even devolution, will march through the lobby with the SNP, which wants independence for Scotland, and with the Liberals, who want to keep the act.
"What a massive display of unsullied principle. The minority parties have walked into a trap.
"If they win, there will be a general election. I am told that the current joke going around the House is that it is the first time in recorded history that turkeys have been known to vote for an early Christmas."
