London's mayor has secured a deal to allow Fulham Boys School to open its doors at the start of the new term in September.
Boris Johnson says he still wants to be blasted by water cannon to demonstrate the weapon poses no risk to the public.
It follows a London MP's decision to retire.
The deadline for applications in the safe Tory seat of Uxbridge passed today, and Boris Johnson's form was on the pile. The seat is so safe, bookies have stopped taking bets on him winning. So, Ria Chatterjee went to find out if Uxbridge is ready for Boris.
Labour's London spokesman and MP for Tooting Sadiq Khan said:
"Boris Johnson's announcement is confirmation of how weak David Cameron is and how out of touch the Tories are.
"When millions of people are struggling under a cost of living crisis, the Tories are turning inwards, jockeying for position in a future leadership contest.
"What Britain needs is a change of direction. For all their squabbles over who leads them, all the Tories offer is more of the same failure."
Mr Johnson has said that if he is elected to the Commons next May he will still serve out his term as Mayor, which ends in 2016.
In his Telegraph newspaper column at the weekend he called for tougher anti-terrorism laws - including a presumption that Britons travelling to Iraq and Syria without notifying UK authorities are engaged in criminal behaviour.

"The law needs a swift and minor change so that there is a “rebuttable presumption” that all those visiting war areas without notifying the authorities have done so for a terrorist purpose."
But Downing Street has poured cold water on the idea, stressing that police and security services are not "pushing" for such measures.
Boris Johnson has applied to be the Conservative candidate for Uxbridge and South Ruislip in the 2015 general election his spokesperson confirmed this afternoon.
Website GetWestLondon says the Mayor of London submitted his name to Conservative Campaign Headquarters this morning, just 48 hours before the deadline.
A committee of five members of the Uxbridge and South Ruislip Conservative Association will whittle the candidates down to three or four on September 5 before announcing their winning candidate on September 12.

London Mayor Boris Johnson is expected to argue that it will benefit the capital and the UK to leave Europe. He's making a speech at an event for business and finance experts later.
A senior MP has accused the firm behind popular cab-hailing smartphone app 'Uber' of unfairly undercutting London taxi drivers by "opting out of the UK tax regime".
Margaret Hodge, the chairwoman of the House of Commons Public Accounts Committee, wrote to London Mayor Boris Johnson demanding to know why Transport for London allowed cars to take bookings through the app without a licence to operate in the capital.
Because the Uber app is operated via a company in the Netherlands called Uber BV, which makes the booking, takes the payment and issues the receipt, corporation tax is payable in Holland, rather than the UK, she said.

The demand for new homes and jobs in the capital is such that we must be ready to start redeveloping Heathrow the moment it moves to its new site. And the sooner we start planning the better. We asked our architects to be as creative as possible and these designs illustrate strikingly different visions of a Heathrow of the future. However the key point is that all these scenarios would potentially create some of the many thousands of new jobs and homes this city will require given London is expected to increase in size by a fifth within the next 15 years. How we deal with that is something we need to be planning for and debating right now. Those discussions must not be delayed.
More doubt has been cast on the prospect of the so-called "Boris Island" Thames Estuary airport plan going ahead.
Favoured by London Mayor Boris Johnson, the estuary scheme, involving a new four-runway airport, is being studied by the Whitehall-appointed Airports Commission.
One of three reports prepared for the commission published today has said of the estuary plan: "Overall, the challenges to transition are considerable and amount to a significant cost and risk to the taxpayer in terms of commercial negotiations, infrastructure development and potential failure."
