Cameron renews NHS funding pledge

David Cameron has used his first major speech since the election to underline government plans to expand seven-day services in the NHS in England.

He committed to a pre-election pledge to increase budgets by at least £8bn a year by 2020, during his speech at a GP surgery in the West Midlands.

Doctors' representatives said without detail the announcement was "empty headline-grabbing".
