Fiona Onasanya has posted a video message online maintaining her innocence, after serving one month in jail for perverting the course of justice.
The disgraced MP was convicted for lying about a speeding offence, but insists she is innocent and will continue to "pursue avenues" to clear her name.
In the video message, she says she is "willing and able" to continue as MP for Peterborough, as a petition to force her to face a by-election begins.
Alongside the video posted to Facebook, YouTube and Twitter, the MP wrote: "What would you do if you knew you were innocent? In every single story, like a coin, there are two sides - now I am not legally restrained - this is mine."
Following her conviction, she resisted calls to stand down from Parliament, sitting as an independent as she spent one month of a three-month sentence behind bars.
Despite being expelled from the Labour Party, she was not subject to automatic removal as an MP as her sentence was less than 12 months.
He denials come after being convicted by a jury at the Old Bailey and having the Court of Appeal reject a challenge against her conviction.
