Onasanya, the Labour MP for Peterborough who lied about who was driving her car when she was caught speeding and tried to pin it on a Russian man who wasn't even in the country at the time of the offence, which she still denies, is jailed for three months.
Incredibly, this is below the (12-month) threshold at which she would have to step down as an MP, and she has previously remarked that she has no intention of resigning, thus leaving the people of Peterborough without representation during this rather crucial period of British politics...
Let's quickly compare this to Chris Huhne, the Conservative (well, Lib Dem, but you know the coalition) MP who claimed his wife was driving at the time of a speeding offence - she took the points and the fine for it voluntarily - which she then backtracked on after their relationship deteriorated, leading to a prosecution for the same offence. Huhne resigned the moment he was charged, and despite pleading guilty got an eight-month sentence (as did his wife).
Charged, resigned, pleads guilty, convicted, eight-month sentence.
Charged, denies, convicted, three-month sentence, won't resign.
