PMQs: Cameron and Miliband on national insurance and taxes
The final session of prime minster's questions in the 2010-2015 parliament saw David Cameron ask his opponent about a potential rise in national insurance under Labour.
Ed Miliband and the prime minister also clashed on the NHS, tax cuts and exchanged sound bites on the economy, health and schools.
They will not meet again in Parliament until after the 7 May elections.
