The British-Pakistani MP for Tooting was 6 points ahead of his Conservative rival Zac Goldsmith with counting almost over.

Official confirmation of Khan’s win is expected after 18:00 BST.

Goldsmith has been accused of participating in a “dirty” campaign by accusing Khan of affiliating with Muslim extremists.

Khan is now widely seen as the most powerful Muslim in Britain, with a budget of £17 billion to spend on the capital for policing, transport, planning and the environment.

The son of a bus driver has pledged to support businesses in London and change planning rules to help increase the number of affordable homes.

Tory MP Mark Field criticized the Goldsmith campaign in an interview with the BBC, stating: “In many ways with Zac, it felt slightly ill at ease to be putting the boot in.”

Supporters of Khan have already begun tweeting congratulations to the new mayor.

Meanwhile critics of Zac Goldsmith and his campaign are calling for him to resign as MP for Richmond Park and North Kingston.
