Hundreds of thousands of health workers walked out on strike today, many for the first time in their lives, in protest at the Government's decision not to give them a recommended 1% pay rise.
Midwives, nurses, paramedics, ambulance staff, and hospital porters and cleaners mounted picket lines across England from 7am for four hours, while action will be taken later today in Northern Ireland.
David Cameron defended the Government's health spending record today as he paid an official visit to Portsmouth during the NHS strikes.
He said: "We spent more on the NHS in this parliament, £12.7 billion more.
"When Labour was proposing to cut it, we protected the NHS budget and I have said we will do exactly the same thing again, protecting the NHS budget in the next parliament."
With thousands of NHS staff expected to go on strike today in a row over pay, here is a list of those hospitals affected.
A fifth of health workers have at least one extra job because they cannot survive on an NHS salary, survey reveals.
