Despite being divorced, she wrote on the social media platform: “22 years later, after humiliations, hurdles and sacrifices, my sons’ father is Pakistan’s next PM.
“It’s an incredible lesson in tenacity, belief & refusal to accept defeat.
“The challenge now is to remember why he entered politics in the 1st place. Congratulations @ImranKhanPTI.”
Jemima Khan was born on January 30, 1974 at Westminster Hospital in London, and is a British television, film and documentary producer, journalist and campaigner.
She is the eldest child of Lady Annabel Vane-Tempest-Stewart and financier Sir James Goldsmith.
Her mother is from an aristocratic Anglo-Irish family, the daughter of the Marquess of Londonderry, while her father was the son of former Conservative MP Frank Goldsmith.
Ms Khan has two younger brothers, Zac Goldsmith and Ben Goldsmith, and five parental and three maternal half-siblings.
She enrolled at the University of Bristol in 1993 and studied English, but dropped out when she married Imran Khan in 1995, before completing her bachelor’s degree in March 2002 with upper second-class honours.
Ms Khan married the former World Cup winning Pakistan cricket captain on May 16, 1995 in a traditional Islamic ceremony in Paris, followed by a civil ceremony on June 21, 1995 at the Richmond Register Office.
Shortly before her wedding to Mr Khan, she converted to Islam and after the marriage, relocated to her new husband’s hometown of Lahore in Pakistan, where she learned to speak Urdu and also wore traditional Pakistani clothes.
She began to increase her support for her husband as he became more involved in the Pakistan Tehreek-e-Insaf (PTI) party, and he became a member of the country’s Parliament in 2002.
But on June 22, 2004, it was announced they were divorcing on amicable terms, with the marriage ending because it was “difficult for Jemima to adapt to the political life of Imran Khan in Pakistan”.
Ms Khan returned to Britain with the couple’s two sons and according to the divorce settlement, the children visit their father in Pakistan during their school holidays.
As part of her heavy charity influence, she established the Jemima Khan Afghan Refugee Appeal to provide tents, clothing, food and healthcare for refugees in the country at the Jalozai camp in Peshawar.
She became a UNICEF UK ambassador in 2001, making trips to Kenya, Romania, Bangladesh, Afghanistan and Pakistan, the last of which saw her help raise emergency funds for the victims of the 2005 Kashmir earthquake.
In 2003, she visited Palestinian refugee camps in Lebanon, Jordan, the West Bank and Gaza to promote the charity Hope and Optimism for Palestinians in the Next Generation (HOPING).
In addition to the charities she supports, Ms Khan also campaigns for social and political causes.
In 2007, she established the Free Pakistan Movement, where she, her family and friends participated in three demonstrations along with thousands of protestors outside Downing Street in opposition to the state of emergency in the South Asia country.
She has also campaigned against the wars in Iraq and Afghanistan.
