The mayor believes the economic recovery should force developers to rethink their commitment to social housing.
A new station will be built at Barking Riverside where a town with a population of 29,000 - the same size as Windsor - is planned.
The Mayor has written to Home Secretary saying he supports the anti-riot measure. The move has infuriated members of the London Assembly.
– Boris Johnson, Mayor of London
Most people would recognise we have built a record number of affordable homes so far, this is just additional to all the other projects that we're doing. We're on track to built 100,000 over this mayoralty and don't forget that it began in the biggest credit crunch that anyone can remember.
Labour say Mayor Boris Johnson's plans to free up planning for brownfield sites are 'too little too late'.
– Tom Copley, Labour, London Assembly
The fact is that Boris Johnson has had six years to get a grip on the housing crisis in London and he's failed to do so. London is only building a third of the homes each year that his own estimates say are needed.
Chancellor George Osborne and London Mayor Boris Johnson were at a former gasworks which has been deserted for 40 years to launch the scheme. They say the site in Tottenham can now be built on after they removed planning restrictions to get more homes built quickly.
Fifty thousand new homes will be built, 40% of which will be affordable, housing 250,000 people.
Fifty thousand new homes are to be built across 20 brownfield sites in London as part of plans to tackle the capital's chronic housing shortage.
The £400m scheme was announced today by Chancellor George Osborne and London Mayor Boris Johnson, and will mean developers are able to bypass planning laws.
Dismissing the challenge at the High Court today, Judge Justice Lang said the real issue in the case was a profound disagreement between the councils and Boris Johnson over housing policy:
I consider it is unarguable that the (mayor's) strategy is so misguided or flawed that it will effectively prevent the (councils) from making appropriate provision for affordable rented housing.
I accept that the strategy may be open to legitimate criticism, but it is plainly within the band on reasonableness.
Nine London councils have lost their legal challenge over the mayor's plan to relax rules for affordable rents in the capital.
Islington Council, with backing from seven other Labour councils and independent Tower Hamlets, tried to overturn an amendment to the London Plan which they believe will squeeze local families out, including those caught by the Government's benefits cap.
Currently councils in central boroughs can restrict rents on social accommodation within new developments to around 40% of the market rent. Under the Mayor's plan, the figure will be raised to 80%.
– David Cameron, speaking to The Sun
I want him to get back in Parliament. I think he's great. It's a bit like football - if you have got a great striker you want him on the pitch.
It's up to him. He can complete as Mayor, or he can stay on as Mayor and come back to the House. I want him on the team.
Following mounting speculation about Boris Johnson wanting to become prime minister David Cameron said:
– David Cameron, speaking to The Sun
It wouldn't be a great job to have if people didn't want it. There is nothing ignoble about wanting my job.
David Cameron has made a plea for Boris Johnson to return to Parliament and run in the next election. The Prime Minister said it is up to the Mayor of London whether he completes his term in City Hall, but wants him "on the team".
David Cameron was speaking in an interview with comedian James Corden, who was guest Editor of The Sun. Running in the next election is "what I think" Mr Johnson should do, Mr Cameron said.
