The Foreign Secretary is unhappy at plans to shut Uxbridge police station in his west London constituency.

London mayor Sadiq Khan claims government cuts leave him with no choice but to close half of London's police station front counters.

His Tory predecessor tweeted:

But a source close to Mr Khan accused Mr Johnson of being a 'stupid hypocrit', saying the former Mayor closed 63 police stations in 2013.

Instead of this petty party politics Boris Johnson should persuade the Home Secretary to give London's police service the funding they desperately need to keep us safe.
