Never one to stay quiet for too long, David Starkey has provoked outrage by comparing the SNP to the Nazis.
In an interview with the Sunday Times (£), the outspoken historian likened the swastika to the Saltire and suggested that a desire to blame England for Scotland’s problems was similar to Hitler blaming Jewish people for Germany’s economic crash.
He said: “We have a political movement that has a single historic explanation for why your country is facing such terrible oppression; it’s either Versailles or the Treaty of the Union.
“You have a particular group of people who are responsible for this; it is either the English or the Jews.”
David Starkey's latest comments have once again provoked outrage
He added: “You have as a symbol the twisted cross: the saltire or the swastika.
“You have a passionate belief in economic self-sufficiency: known by the Nazis as autarky and the Scots as oil.”
SNP MP Kirsten Oswald blasted the 70-year-old as “little more than a serial utterer of bile and bilge”, according to The Independent.
She added that his comments were "irresponsible" and "deeply offensive to the Jewish community, the half of the Scottish electorate who voted SNP last month and 60 per cent who currently intend to vote SNP next year".
Speaking on the Andrew Marr Show this morning, SNP MP John Nicholson said: "He says the St Andrews Flag, the saltire flag, looks like a swastika. He seems not quite to understand the origins of he calls it the 'twisted cross' rather than the cross that St Andrew was crucified on out of respect for the original cross.
"It's offensive to Christians, to Jews and obviously Scots.”
The comments did not go down well on social media either.
One person on Twitter felt the best way to object to someone comparing people to the Nazis was to compare that person to the Nazis.
This is not the first time Starkey has drawn such comparisons - in 2012 he said that Alex Salmond was like a "Caledonian Hitler".
He said: "If you think about it, Alex Salmond is a democratic Caledonian Hitler, although some would say Hitler was more democratically elected.
"[For him] the English, like the Jews, are everywhere."
