Former MSP Tommy Sheridan is to launch a new bid to overturn his perjury conviction.

The 50-year-old is set to take his case to the Scottish Criminal Cases Review Commission (SCCRC) in a fresh attempt to clear his name.

Sheridan was jailed for three years in January 2011 after being convicted of lying under oath during his successful defamation action against the News of the World in 2006.
