One way or another, Sikh women have had a big impact on Boris Johnson’s life.

After 25 years of marriage and four children, he is splitting up from Marina Wheeler, who is the daughter of the late BBC Delhi correspondent, Sir Charles Wheeler, and Dip Singh, whose first husband was Khushwant Singh’s younger brother, Daljit Singh.

Now, the woman who has won an historic victory in the supreme court in London is a Sikh woman, Gina Miller, who was born Gina Nadira Singh in British Guyana on 19 April 1965 to Savitri and Doodnauth Singh.

Her father later became Attorney-General of the newly independent Guyana. Gina was sent to England at the age of 10 and studied at the fee-paying private Moira House Girls’ School in Eastbourne.

Three years ago she took on Theresa May over her government’s decision to trigger article 50 of the Brexit Bill without parliamentary oversight — and won in the Supreme Court.

Her battles against the Brexit lobby have made her one of the most hated figures in the country as the EU debate has become increasingly acrimonious and she is not able to move around without bodyguards.

She is on her third marriage and has three children.

She is also much admired for her feisty attitude to life and leading a determined fight against Boris’s policy of exiting the UK without a deal.

Speaking outside the Supreme Court on Tuesday, Miller, entrepreneur and Brexit campaigner, said the Prime Minister was not above the law.

“Today is not a win for any individual or cause, it’s a win for parliamentary sovereignty, the separation of powers and the independence of our British courts,” she said.

“Crucially, today’s ruling confirms that we are a nation governed by the rule of law. Laws that everyone, even the Prime Minister, is not above. MPs should turn up for work tomorrow and get on with scrutinising this government.

“We have had twice in three years to come to the Supreme Court, to ensure that the government does not put itself above the law.

“The ruling today speaks volumes.

“This Prime Minister must open the doors of parliament tomorrow. MPs must get back and be brave and bold in holding this unscrupulous government to account.”
