Over a million public sector workers are taking industrial action against the Government in a series of rows over pay, pensions, jobs, conditions and spending cuts, according to union leaders - a figure disputed by the Government.
A government minister has said fewer than 500,000 people are estimated to have taken part in today's public sector strike, a significantly lower number than union leaders have claimed.
Cabinet Office Minister Francis Maude, who is responsible for the Civil Service, said: "Our official estimates are that fewer than half a million took part in this strike action – well short of the inflated claims of union leaders.
"Within the Civil Service, there has been the lowest recorded turnout for a national strike," he added.
Union leaders said they were "overwhelmed" by support after a strike by public sector workers caused widespread disruption.
David Cameron, Michael Gove and other Government figures depicted in a variety of unflattering manners by striking public sector workers.
