How should an MP be punished?

Fiona Onasanya was driving her car at 41mph in a 30mph back in 2017, something for which she'd usually get a fine and some points. Rather than take the hit herself, she got her brother to admit fault, in a similar fashion to Chris Huhne and Vicky Pryce a few years ago. Those two got 8 months in prison each (most likely down to two with good behaviour).

However, Onasanya, a lawyer and Labour MP (she's been kicked out now), has managed to get off with a 3 month sentence despite also having been texting while speeding, leaving her brother pleading guilty and getting a 10 month sentence.

Personally, I think the more involved in the law you are, the higher the standard of behaviour you should be held to as you can't be given as much benefit of the doubt. Huhne and Pryce received the same sentences as each other which was perhaps unfair on Pryce with Huhne being in government, but then she did deliberately try to court the media to prejudice the trial so maybe that balances that. Onasanya, being an MP with a legal background, I would expect to be hit harder than those two, but somehow she has less than half their sentence, and feels she has grounds to appeal further. Her hapless brother has over triple her sentence, which makes no sense to me. Clearly one's knowledge of the legal system and ability to make a case has an effect on a sentence, but these discrepancies are ridiculous. This is also ignoring that she was texting while speeding too - why hasn't she got the longest sentence of the four?

She's also holding onto her seat as an independent, and her constituents will have to wait for her appeal before they can petition to recall her.

As an MP yes. but as a lawyer then no as that falls to the SRA. If/ when she is struck off then thats her entire career gone for life.

The judge will have applied the sentencing guidelines.

Apparently someone thought the same I did and made a complaint so now the sentence is being reviewed for being too lenient. Only one person need make a complaint and the Attorney General will review it, which is pretty cool, if potentially very time consuming for them.

No political motive of course, I mean the last thing on the Tory AG's mind will be any sort of cheap point scoring against a Labour MP. Thank goodness.
