An e-petition calling for full disclosure of government documents relating to the 1972 building workers’ strikes and trials of workers in Shrewsbury is due to end.
Building workers held their first national strike in 1972 over pay and safety.
Several workers were victimised and imprisoned in the aftermath.
The government has refused to release files relating to the strike, even though more than 30 years have passed.
The deadline is 27 June.
