British actor Ricky Tomlinson submitted a petition at the offices of U.K. Prime Minister David Cameron on Monday (16Dec13) as part of an ongoing battle to clear his name over a 1970s conviction. The Mike Bassett: England Manager star was sentenced to two years in prison in 1973 on a charge of conspiracy to intimidate for his part in a building workers' dispute in Shrewsbury, England. He was hoping to overturn his conviction using documents relating to the case which were due to be made public last January (13), but former U.K. Justice Secretary Kenneth Clarke extended the embargo, prompting Tomlinson and a group of activists to launch a campaign. The Shrewsbury 24 drive garnered a petition of more than 100,000 signatures, which was handed in at Downing Street on Monday. The achievement means the issue will now be debated in parliament.
