Billionaire businessman Anand Mahindra in his reaction to to Indian-origin Rishi Sunak as the next Prime Minister of the United Kingdom, recalled a quote by famous former British Prime Minister Winston Churchill pointing "that he had proved to be false."

Mahindra said, Churchill had supposedly remarked about the calibre of Indians, which he pointed out, proved to be wrong with Sunak’s appointment.

Sunak becomes the 57th prime minister of the UK and the first person of colour to lead the country. He is also UK’s first Hindu premier but the former chancellor to the exchequer has rarely spoken about his religion despite being a practising Hindu.

“In 1947 on the cusp of Indian Independence, Winston Churchill supposedly said “…all Indian leaders will be of low calibre & men of straw." Today, during the 75th year of our Independence, we’re poised to see a man of Indian origin anointed as PM of the UK. Life is beautiful," Mahindra said on Twitter.

Sunak will take charge as Britain's first Indian-origin Prime Minister after an audience with King Charles III on Tuesday, a day after he was elected the new leader of the Conservative Party in a historic leadership run.

Outgoing Prime Minister Liz Truss chaired her final Cabinet meeting at 10 Downing Street on Tuesday morning before making her way to Buckingham Palace to formally tender her resignation to the 73-year-old monarch.
