Public sector strike: 'Enough is enough' says Unison's Dave Prentis

More than a million public sector workers are expected to strike in a series of disputes with the government over pay, pensions and job cuts.

Teachers, council staff, firefighters and civil servants are among those walking out on Thursday.

Prime Minister David Cameron has condemned the disruption and promised to tighten strike ballot laws.

Dave Prentis from Unison, which represents members in local government, healthcare, colleges and schools, said they were taking action because ''enough is enough''.
