Firefighters will stage a 12-hour strike today in the latest of a weekend of action over a long-running dispute with the Government over pensions.
Members of the Fire Brigades Union in England and Wales will strike between 2pm today and 2am tomorrow, and between 10am and 3pm tomorrow.
FBU members walked out for five hours yesterday, forcing fire authorities to make alternative arrangements for fire cover.
The Government denied union claims that ministers had drawn up alternative proposals six weeks ago, but had been "sitting" on them ever since.
