A former MP who fraudulently used taxpayers' money to fund his cocaine habit has had a bid to appeal his sentence denied.

Jared O'Mara, who was the MP for Sheffield Hallam, was jailed for four years in February after being convicted of six counts of fraud.

The 41-year-old had tried to claim £52,000 of taxpayers' money for constituency work that was never done and jobs that did not exist.
