Humza Yousaf was confirmed as first minister of Scotland on Tuesday, becoming the first person of colour to head the Scottish government, and the first Muslim national leader in any Western democracy.
The milestone comes five months after the United Kingdom got its first Hindu prime minister, Rishi Sunak. Britain's capital city is headed by London Mayor Sadiq Khan, the son of Pakistani immigrants.
All three politicians reflect the accelerating diversification of politics in Britain, a country whose imperialist past has — uncertainly and sometimes painfully — forged a multi-ethnic present.
"There's an expectation now, or a familiarity with diversity in British politics, that we don't see in other European countries," said Sunder Katwala of British Future, a think-tank that studies identity and race.
Lawmakers in the Edinburgh-based Scottish Parliament voted on Tuesday to confirm 37-year-old Yousaf as first minister, a day after he was elected leader of the governing Scottish National Party.
Scotland, a country of 5.5 million people, is part of the UK, but has a semi-autonomous government with broad power in areas including health and education.
In an acceptance speech on Monday, Yousaf said he was "forever thankful that my grandparents made the trip from the Punjab to Scotland over 60 years ago".
"As immigrants to this country, who knew barely a word of English, they could not have imagined their grandson would one day be on the cusp of being the next first minister of Scotland.
"From the Punjab to our Parliament, this is a journey over generations that reminds us that we should celebrate migrants who contribute so much to our country."
The UK has not always heeded that reminder: migrants have often experienced racism and hostility both covert and overt.
That hostility remains government policy for people who arrived by unauthorised means: detain and deport anyone who crosses the English Channel in small boats and send some asylum-seekers on a one-way trip to Rwanda.
But British society and politics have grown markedly more diverse.
About 18 per cent of the population is non-white and many people have roots in countries the British Empire once ruled, including India, Pakistan and Caribbean nations such as Jamaica.
Yousaf was born in Glasgow in 1985. His father's family came from Pakistan, his mother's from East Africa, part of an exodus of South Asian families who faced post-independence discrimination.
One grandfather worked in a Singer sewing machine factory, and a grandmother was a Glasgow bus conductor.
Yousaf joined the pro-independence SNP in 2005, inspired partly by its then leader Alex Salmond's opposition to the United States-led invasion of Iraq, which the UK under then prime minister Tony Blair had joined.
Yousaf had said he felt independence from the UK was the only way to ensure Scotland would not become embroiled in another illegal war.
Opposition politicians are brutal about his political record, citing Scotland's long waiting times for healthcare and serious drug-addiction problems.
Still, Scottish Labour Party leader, Anas Sarwar, also a Muslim Glaswegian, said "regardless of your politics, this is a significant moment for Scotland".
Yousaf has spoken about the strength he draws from religion, but his Muslim faith drew little comment during the SNP contest. Instead, it was the faith of his opponent, Kate Forbes, an evangelical Christian, that drew attention.
She was criticised after disclosing her opposition to same-sex marriage, which is legal in Scotland and which Yousaf supports.
Britain is not the only European country whose politics are growing more diverse. Irish Prime Minister Leo Varadkar has an Indian father and Portuguese leader Antonio Costa has South Asian roots.
But Britain has seen rapid political change. Forty years ago, there were no ethnic minority lawmakers in the British Parliament. Now, there are 65 of them — 10 per cent of the total.
The foreign, home and trade secretaries in Sunak's government are all people of colour.
Katwala said a notable feature of the diversification is that "it's happening in all parties" — Yousaf is a Scottish nationalist, Sunak a Conservative, Khan a Labour Party member.
"There's a confidence — among British ethnic minorities, but (also) reciprocated broadly — that politicians who are Black, Asian or white can represent everybody, not just their own group."
