Labour leader Jeremy Corbyn promises to support Shrewsbury 24 campaign

The Labour party leader made the pledge after praising the Hillsborough victims family members for their long campaign for justice.

In the 1960s and 70s the UK’s building companies were making millions re-building the country, but building workers faced the most dangerous working conditions and poorest wages of any trade.

In the summer of ’72, for twelve weeks, 300,000 building workers launched their industry’s first national all-out strike to end cash “lump” wages and seek better pay by using the controversial tactic of ‘Flying Pickets’.

The partial success of the strike, and the methods used, enraged the construction industry and government, and culminated in the arrest of 24 builders in North Wales who were charged with offences including conspiracy to intimidate and affray.

The “Shrewsbury 24” were prosecuted at Shrewsbury Crown Court in 1973 and three were jailed, Ricky Tomlinson, Des Warren and John McKinsie Jones.

Campaigners say the men were victims of a miscarriage of justice and the convictions against them should be quashed.

The events surrounding the strike are still making headlines to this day, and 43 years on, the high-profile Shrewsbury 24 Campaign, led by picket turned actor Ricky Tomlinson is still seeking to overturn the unjust prosecution of the 24 building workers.

Mr Corbyn said he would support the Shrewsbury 24 campaign as they continue to battle for "truth and justice" and promised them both if the Labour party was to win the next election.
