Hertfordshire MPs Peter Lilley and Anne Main will take part in a Question Time style EU referendum debate tonight.
The MPs for Hitchin and Harpenden and St Albans respectively are both backing Brexit.
They will join Graham Colley, chair of the Liberal Democrat lawyers association and businessman Gerald Corbett for the event chaired by the Right Reverend Stephen Venner.
And following the spirit of the well-known tv programme the public are being invited to submit to put to the panel before the debate starts.
Canon Kevin Walton of St Albans Cathedral said: "People are quickly realising just how important the vote on Europe is not just for the next few years, but for the next generation."
Entrance is free for the debate at St Albans Cathedral which starts at 8pm. Doors open at 7.30pm.
