Jeremy Corbyn, Labour leader

Jeremy Corbyn has hit back at David Cameron after the Conservative leader mocked the left-winger's dress sense during a heated exchange at Prime Minister's Questions (PMQs). Cameron claimed his mother would advise the Labour leader to "put on a proper suit, do up your tie and sing the national anthem".

The unsolicited advice came after a Labour MP urged the prime minister to "ask your mother" during an argument over the NHS and the junior doctors' contract dispute in the House of Commons.

The MP was making a reference to Mary Cameron's decision to sign an anti-cuts petition in Oxfordshire. Corbyn has now claimed Cameron issued the personal attack because of the prime minister is envious of his attire and shopping facilities near his north London home.

"He's actually jealous of the jacket," the winger quipped. "You know what he's really jealous of? That I can go shopping in the great shopping centre of the world, Holloway Road. And he's stuck with Bond Street."

The comments were captured by a Press Association video team as the Labour leader prepared for a broadcast interview in Birmingham. Corbyn was in the West Midlands to launch Labour's Police and Crime Commissioner (PCC) election campaign alongside shadow home secretary Andy Burnham.

PCC elections

The party released an analysis of House of Commons' Library figures to coincide with the event. The research claimed police forces in England and Wales will receive £30m ($41m) less in cash in 2016-17 due to cut in the central government grant to forces.

"The public have not been told the truth about police funding and crime figures. Budgets for next year have not been protected in real terms. They are being cut again – for the sixth year in a row – at a time when the country is facing increasing risks," Burnham told MPs. "The truth is that the police is being cut whilst crime is rising. They are cutting the fire service and the border force even more deeply.

"Tory cuts that are putting your safety at risk – that's the message that we will take into the PCC elections. I defy the government to stand by its claim that it is protecting police budgets in real-terms."

But Home Secretary Theresa May said: "As the chancellor set out in the Autumn Statement, overall police spending will increase from nearly £11.4bn this year to £12.3bn at the end of the Spending Review period. This is an increase of just under 8%, or £900m in cash terms, and a protection in real terms over the course of this Parliament – if PCCs maximise their precept.

"Funding for individual PCC budgets, which includes funding from central government and from local taxpayers through the precept, will be protected in cash terms.

"And we will provide substantial additional investment over the period in transformation funding, to improve police capabilities to deal with modern threats like terrorist firearms attacks, cyber crime and other emerging threats."
