Labour must 'reach beyond its own activists'

New London mayor Sadiq Khan has said that he felt disappointed by how the Conservative campaign was run during the mayoral election and referred to the tactics used as "nasty".

Speaking on the BBC's Andrew Marr show he said: "I was disappointed that the Conservative party chose to have a campaign that was nasty, that was negative and that was divisive."

Sadiq Khan's first public engagement since being installed as Mayor of London on Saturday will be at a Holocaust Remembrance Day ceremony.

Mr Khan will appear at the event in Barnet, north London, alongside a number of prominent figures in the Jewish community to commemorate the millions slaughtered during the Nazi genocide.

Up to six millions Jews are known to have been killed in the Holocaust during the Second World War.

The appearance comes after Mr Khan took a strong stance against anti-Semitism during the racism scandal which engulfed the Labour Party in recent weeks.

Sadiq Khan, who was signed in as Mayor of London at Southwark Cathedral earlier today, said he hopes his election victory inspires more Muslims to enter mainstream politics, despite the "divisive" campaign against him.

The new mayor said he had been told that parents had warned their children against a career in politics following the bitter campaign where Zac Goldsmith and other Tories tried to link him to Islamic extremists.

He said his success was down to a "positive" campaign which offered solutions to problems facing Londoners.

He said: "I'm mayor of London now. I've got bigger things to worry about than Zac Goldsmith's campaign.

"It's for them to ask themselves the question, how is it that in the most diverse and fantastic city in the world they chose to have a negative, desperate and divisive campaign?"

Labour leader Jeremy Corbyn was conspicuously absent from Sadiq Khan's swearing ceremony, opting instead to visit Bristol to congratulate the city's newly elected mayor Marvin Rees.

"I'm sure I'll be seeing Jeremy over the next few days," Mr Khan told ITV News.

US presidential hopeful Hillary Clinton has congratulated Sadiq Khan on his election victory as mayor of London.

The frontrunner for the Democratic nomination hailed Mr Khan on Twitter as a "champion of workers' rights and human rights".

Congratulations also came from a swathe of global political figures, including New York Mayor Bill de Blasio, Paris Mayor Anne Hidalgo, and Ahok Basuki Purnama, the governor of Jakarta.

French Prime Minister Manuel Valls also added his best wishes: "Congratulations Sadiq Khan on your outstanding victory in London. Looking forward to welcoming you in France."

Newly-elected London mayor Sadiq Khan said he "can't quite believe the last 24 hours" as he addressed the crowds at his official swearing in ceremony at Southwark Cathedral.

"I'm only here today because of the opportunities and helping hand that our city gave to me and my family."

Mr Khan also repeated his vow to be a "mayor for all Londoners" during the short, multi-faith service.

"I want to start my mayoralty as I intend to go on. I want to lead the most transparent, engaged and accessible administration London has ever seen," he said.

Newly elected London mayor Sadiq Khan has left for his first day in his new job pledging to be a "mayor for all Londoners".

Saying he was "tired" after weeks of campaigning and a result which came after midnight, he told reporters outside his home his priority was "to try to get to the office".

Newly elected London mayor Sadiq Khan has hailed the announcement that he had won the capital's mayoral race as a "victory for hope over fear and for unity over division".

In a message of thanks posted to supporters on his Twitter page in the early hours of Saturday morning, shortly after he broke the Conservatives' eight-year hold on City Hall, Khan also hailed the win as "an amazing victory".

He also linked to his website where his full message of thanks was printed:

Britain First mayoral candidate Paul Golding turned his back on Sadiq Khan as the new London mayor gave his victory speech on Saturday morning.

Earlier on in the elections results, the announcement of Mr Golding's 31,372 votes was greeted by cheers from within the crowd.

But as Mr Khan stepped up to the microphone to give his speech, Mr Golding turned his back away from the audience and remained facing the wall until the mayor finished.

Congratulations for new London Mayor Sadiq Khan have come in from Labour MPs.

Streatham MP Chuka Umunna and former Labour leader contender Yvette Cooper took to Twitter to congratulate Mr Khan, who beat rival Zac Goldsmith on Saturday morning to the mandate.
