Shewsbury 24 justice campaigners hailed a big leap forward yesterday in their quest to expose a vicious Establishment conspiracy against innocent trade unionists.

MPs voted to open all secret files on the case following a historic Commons debate 40 years after three Shrewsbury pickets were jailed and 21 others tried on trumped-up conspiracy charges.

Amid passionate calls for justice, MPs voted by 120 to three to demand the lifting of the government ban on publication of papers held on spurious grounds of "national security."
