Angus Struan Carolus Robertson (born 28 September 1969) is a Scottish politician serving as the Cabinet Secretary for the Constitution, External Affairs and Culture since 2021.

Robertson resigned as SNP Depute Leader in February 2018, before launching the pro-independence think tank Progress Scotland in 2019, alongside Mark Diffley.

He was educated at Broughton High School, Edinburgh and the University of Aberdeen, where he graduated in 1991 with an MA Honours degree in politics and international relations.

After university he embarked on a journalistic career, and worked as a foreign and diplomatic correspondent in Central Europe for the BBC World Service.

[6] In 2007 Robertson pushed for a UK-wide referendum on the Lisbon Treaty, something that the SNP opposed because it entrenched EU control over Scottish affairs.

[10][11] In 2018 it was revealed that Robertson had been contacted a decade ago by staff at Edinburgh Airport about the alleged behaviour of then First Minister Alex Salmond.

[14] In January 2016, Robertson said that British Prime Minister David Cameron should admit to British involvement in Saudi Arabian-led intervention in Yemen: "Isn't it time for the Prime Minister to admit that Britain is effectively taking part in a war in Yemen that is costing thousands of civilians lives and he has not sought parliamentary approval to do this?

[16] During the 2017 general election Robertson told the media that "Tory is a four letter word in Scotland", but amid a backlash to Nicola Sturgeon's decision to call for a second independence referendum,[17] he lost his Moray seat to Douglas Ross of the Scottish Conservatives.

"[19] After losing his seat, Robertson resigned as a Depute Leader of the SNP and established Progress Scotland, a pro-independence think-tank.

[23] Cherry dropped out of the contest, citing an unwillingness to make her staff unemployed in a pandemic, and Robertson won the party's nomination.

However, when only 77% of households returned the census - compared with a rate of 97% for the one in England and Wales the previous year - Robertson extended the deadline at a cost of nearly £10 million.

[27] Robertson said the Russian invasion of Ukraine was partly to blame but told the Scottish Parliament there were "potentially serious consequences for not completing a census".

[28][29] Opposition politicians labelled Robertson's handling of the census "nothing short of disastrous" and said the SNP had been foolish not to hold it at the same time as the rest of the country when there was a significant amount of UK-wide publicity about the event.

In September 2014, Robertson – and three of his SNP colleagues – were criticised by The Scotsman and Labour MPs after they missed a vote on an amendment to the bedroom tax that would have exempted certain people in certain circumstances - with critics making the point that the SNP had made opposition to the bedroom tax a central part of its campaign for a yes vote in that year's independence referendum.

Since 2014, this has added around 330,000 voters to the electorate, with a likely net gain of over 100,000 for independence.”[38] His remarks were condemned as tasteless by opposition parties and his successor as MP for Moray, Douglas Ross, described them as, "Disgraceful and deeply disappointing comments from Angus Robertson, suggesting that the most vulnerable age group, who have been hardest hit through the tragic loss of so many lives throughout the pandemic, are a boost to his independence obsession.
