“Special Diwali wishes to the ‘living bridge’ of UK Indians, as we transform our historic ties into a modern partnership,” he tweeted.
The announcement was met with a similar response in Australia.
For many Indian Australians, Mr Sunak's appointment coinciding with Diwali (festival of lights) provided the perfect moment to celebrate.
In a tweet, Australia India Institute CEO and former Labor Senator Lisa Singh called the news 'significant'.
Ms Singh, who was a senator from 2011-2019, was the first female Australian member of parliament of Indian origin.
She told SBS Hindi, “This really speaks to the success of the vast Indian diaspora across the world."
“Australia’s parliament is similarly reflecting the growing success of the Indian diaspora. That’s good for democracy and multiculturalism. Sunak’s rise to Prime Minister of Britain is significant, whatever side of politics one sits on," she opines.
