Lucy Connolly will speak at the second and final day of the Reform UK party conference.
The 42-year-old childminder was released from jail last month after being handed what is believed to be the longest prison sentence for a single social media post.
She was sentenced to 31 months in jail over a comment made in the wake of the Southport attack.
Mrs Connolly will speak on the main stage of Reform’s conference in a special live recording of The Telegraph’s Planet Normal podcast with Allison Pearson and Liam Halligan.
In her first interview following her release from jail, she accused Sir Keir Starmer of holding her as a political prisoner.
