Ricky Tomlinson has handed in a 100,000 signature petition to Downing Street, calling for the quashing of his 40-year-old conviction over a builders' strike.
Tomlinson was among a number of former pickets, convicted over their actions during the dispute in the early 1970s.
They want their names cleared, after being found guilty in what they believe was a politically-motivated and unjustified prosecution.
