Mr Khan said that even dropping the changes to the funding formula would not be enough to ensure the Met was properly resourced to deal with the threat of terrorism and rising violent crime.”The Home Office has already made the Met find £600 million of savings following cuts since 2010.”Their plans to make the Met find a further £400 million of savings on top of this over the next few years will have a big impact on policing in London,” he said.”If the Government are serious about keeping all Londoners safe then they need to guarantee that they will fully fund the Met – which means real terms increases, cancelling the planned £400 million of cuts and giving London the full allocation of national, international and capital city funds.”The outgoing chief constable of Lancashire, Steve Finnigan, said forces across the country had reached a “tipping point” as a result of past spending cuts.Mr Finnigan, the UK’s longest serving chief constable, told The Guardian he understood the need for the police to make a contribution during a period of austerity but that the cuts had been “too quick and too deep”.

The cracks are appearing in policing,” he said.”We are at a tipping point and we need to have an honest conversation. I do think people are less safe in this country now and I say that with a really heavy heart.” “I am sure we can become more efficient over the next few years.”I am sure we can save costs and money in parts.”But, no, I do not believe the Metropolitan Police should suffer large cuts.” Want the best of The Telegraph direct to your email and WhatsApp?
