The disgraced Peterborough MP Fiona Onasanya could be released from prison today - less than four weeks after she was jailed.
The MP was sentenced for three months for perverting the course of justice after lying to police to avoid a speeding charge.
She's expected to be let out of jail under an early release scheme.
It comes just a day after a complaint to the Attorney General's Office ruled her prison sentence as not unduly lenient.
Onasanya was kicked out of the Labour Party over the case and refused to stand down and trigger a by-election in her seat.
She is expected to be released from HMP Bronzefield in West London on Tuesday under an early-release scheme and could appear in the Commons for tomorrow's crucial Brexit voting.
The Daily Mail reported that Onasanya could be made to wear an ankle tag as part of her early release programme.
The 35-year-old solicitor was jailed on January 29 after she was convicted at the Old Bailey.
