Election 2015: David Cameron promises 'seven-day NHS'

All hospitals in England will provide "a truly seven-day NHS" by 2020 if the Conservative party is re-elected at the next general election, David Cameron has said.

At the party's spring forum in Manchester, Mr Cameron said that more hospitals must provide top-level treatment at the weekend, starting with emergency care.

Labour said the plans, aimed at cutting weekend mortality rates, were not credible without further investment in the National Health Service.
