Mitcham police station is set to close at night, according to a confidential document which lays bare the scale of properties to be sold by the Met.

A restricted Metropolitan police report, leaked to the Evening Standard, suggests 31 out of 32 London boroughs will be left with one station manned 24 hours a day.

In Merton, Wimbledon will retain a 24-hour manned police station, currently based in Queen's Road in the town centre.

But Mitcham police station, opposite Cricket Green, will be downgraded into a part time police station.

Sixty police stations would be lost across the capital, with Westminster the only borough to have two open all night, down from six currently.

Merton Council’s leader, Stephen Alambritis, said he has been given no indication of whether Mitcham or Wimbledon was more likely to be sold or scaled down by the police.

He said: “We want both stations to remain open. This is particularly important for a borough like Merton which has such a diversity – Wimbledon and Mitcham have different needs.

“We also need assurances about what a ‘part-time’ police station means – is it 20 hours? Eighteen hours?”

The proposals also confirm previous reports by the Wimbledon Guardian that safer neighbourhood police offices will be sold off.

Instead, community police teams will have nine "access points" across the borough in council-run buildings, including Merton Civic Centre in Morden.

Government cuts mean the Met needs to save £500m by 2015 and plans have already been announced to sell off its iconic headquarters in Scotland Yard, near St James’s Park, to a smaller facility in Whitehall.

The Mayor’s deputy mayor for policing, Stephen Greenhalgh, and the Met’s Assistant Commissioner, Simon Byrne, will discuss the new policing strategy at a public meeting in Merton Civic Centre on Tuesday, February 26 at 6pm.
