Two London MPs have officially joined the race to be the next London Mayor but has one of them chosen the worst Twitter hashtag of the day to launch his campaign?

After years of speculation, MP for Tooting and former shadow justice secretary Sadiq Khan has announced his bid to be the Labour candidate for the top job at City Hall.

He tweeted: “I'll roll up my sleeves and fight for all Londoners.”

He also told London Live: “I’m really excited today announce that I want to be Labour’s candidate to be mayor of this great city.

“London has made me, my family, who we are. I wouldn’t have got to go to university if it wasn’t for the teachers at my school.

"My parents wouldn’t have been able to have a council property if it wasn’t for the generosity of this city. I went on to become a lawyer and run my own business and this city has made me who I am.”

Mr Khan is using the somewhat cringe-worthy hashtag #TogetherWeKhan to support his campaign.

To get the Labour selection for the mayoral race Mr Khan will have to compete with colleague Diane Abbott, the MP for Hackney North and Stoke Newington, who has also thrown her hat into the ring.

Ms Abbott said: “Hard times call for a campaigning mayor. Now more than ever our city needs a mayor who will stand up for the interests of those increasingly left behind.

"But, as the MP for Hackney, I have always worked to bring all our communities together. And that is the kind of mayor that I will be.

"Above all, I will be the genuinely independently minded mayor that London needs."

This Is Local London: Labour MP Diane Abbott is to run for the leadership of the party

Ms Abbott doesn’t seem to have chosen a nauseating hashtag for her bid, so feel free to suggest one for her in the comments below or on Twitter @local_london.

Other Labour hopefuls include ex-MP for Dulwich and West Norwood and former culture secretary and Olympics minister Dame Tessa Jowell, MP for Tottenham David Lammy and journalist Christian Wolmar.

Whoever is picked by Labour will be up against a new Tory rival next May when current Mayor Boris Johnson steps down after his second term ends.
