A ballot of teachers in the NASUWT trade union has failed to meet the turnout threshold for strike action, despite broad support from those who did vote.
Although around nine in 10 members voting in the ballot supported strikes and action short of a strike, turnout nationally was just 42 per cent, below the threshold of 50 per cent required by law.
In the ballot of state school staff in England, 88.5 per cent of voted in favour of strikes and 94.1 per cent voted in favour of action short of the strike, but the turnout figure means neither can go ahead.
Overall, the figures mean only around 37 per cent of eligible members voted to strike.
