Labour’s mayoral candidate Sadiq Khan has warned that his Tory rival’s negative campaign is putting ethnic minorities off taking part in politics.

The Tooting MP told the Huff Post UK he had spoken to Muslims who would not want their children standing for election because of the smears levelled at him by his opponent and other media outlets.

These include suggestions Khan associates with hate preachers and the family jewellery of ethnic minorities would be under threat if he became London Mayor.

Khan also hit back at claims from Zac Goldsmith that he would be Jeremy Corbyn’s man in City Hall, insisting he is not the Labour leader’s “patsy.”

The Labour man is currently the favourite to succeed Boris Johnson as London Mayor on May 5.

Speaking about Goldsmith’s campaign, Khan said: “In the London that you and I know and love, in a city where you’ve got Londoners of Islamic faith, Jewish, Christians, Hindus, Sikhs, Buddhists, those who aren’t members of an organised faith, black, white, lesbian, gays – it’s not just tolerating difference, but respecting it, not to divide communities by sending out direct mail suggesting to Londoners of Hindu faith that Sadiq Khan will nick your gold.

“I’ve got a thick skin, I’m used to much worse but it’s not a question of how it makes me feel, it’s the impact it has on voters. When I’ve spent my entire adult life trying to encourage, enthuse, cajole minorities – ethnic minorities, religious minorities – to get involved in mainstream politics, to get involved in civic society, to have a mainstream candidate having the most desperate, divisive politics and strategy of any mayoral candidate since 2000, I’m disappointed in Zac. He’s a nice guy, he’s a decent guy, I get on with him, I’ve got his mobile number in my phonebook.”

One line of attack aimed at Khan has been his association with Suliman Gani, an imam at the Tooting Islamic Centre, who has spoken out against increased rights for homosexuals and claimed women should be “subservient” to men.

The Guido Fawkes blog has repeatedly questioned the strength of relationship between Khan and Gani, with the pair believed to have spoken at the same events on at least nine occasions.

Khan said: “You won’t be surprised to hear I don’t spend my life looking at what Guido Fawkes might be saying.”

He added: “When I first stood for Parliament in 2005 there were extremists outside the mosque I had prayed in all my life saying that voting was haram, anybody who took part in my election was going to hell and I was definitely going to hell because I was taking part in what was called man-made law.

“I voted for same-sex marriage – that very imam that Guido Fawkes claims is close to me said horrible things about me, publicly, and I was condemned in no uncertain terms by him and others and had a fatwa put out against me.

“I had to discuss with my daughters police protection and safety and that sort of stuff. I’ve said, and it’s not a flippant line, it’s something I believe quite strongly about, that I will be the British Muslim who take the fight to the extremists.”

Khan questioned the tactics used by his opponents, warning that such a focus on his religion could have a lasting impact on community relations in the capital.

He said: “How do you think they feel when – and I say this without hubris or arrogance – a mainstream British Muslim, someone who has spent his life lecturing British Muslims about getting involved in mainstream society and civic society is treated this way?

“I’ve already had people approaching me saying ‘you know, do you really think I’m going to encourage my nephew and niece, son and daughter, to get involved in politics if this is the way that you’re treated?’

“That’s why I’m disappointed in Zac. Zac should know better and Zac does know better and one of the things when you’re a candidate is you receive advice all the time.”

Another attack from Goldsmith is that vote for Khan is a vote for Corbyn. Last week Boris Johnson claimed the “semi-Marxist, Hugo Chavez worshipping, high-taxing, high spending, garden grabbing, Chateau Neuf du Pape swilling, bendy-bus fetishists” who run Labour would be boosted by Khan winning the London Mayor election.

Khan insists he would stand up to his party leader if he felt it was in the best interest of Londoners.

He said: “Jeremy Corbyn gets the housing crisis, he understands the importance of reducing inequality.
