Election 2015: Tories vow cash boost for NHS

David Cameron is to confirm plans for an extra £8bn for the NHS in England by 2020, if the Conservatives win the election.

Labour says the "unfunded" pledge is a sign of a Tory campaign in panic. It has promised an extra £2.5bn a year, funded by a "mansion tax".

The Lib Dems have also pledged £8bn, funded by scrapping some tax relief.
