DAVID CAMERON plumbed the depths of playground politics yesterday when he responded to serious questions about the NHS with insults to Jeremy Corbyn’s over his dress sense. 

The 49-year-old Prime Minister was strongly criticised for his childish response to scrutiny over the funding crisis facing health services in his own constituency.

The tetchy Tory snapped when Labour backbencher Carolyn Harris heckled him about his mum’s involvement in anti-cuts protests.
