ITV News' Political Editor Tom Bradby will be joined on The Agenda tonight by Labour deputy leader Harriet Harman, actor Sir Patrick Stewart, historian Andrew Roberts and columnist Rowan Pelling.
The panel will discuss three topics: As McAlpine plans to sue 10,000 tweeters, is there something about Twitter that encourages bad behaviour?; the EU – why can’t we make our peace with it?; and, with the success of 50 Shades of Grey and Thursdays in the Park, is eroticism back in fashion?
The Agenda will be on ITV1 at 10.35pm, after the News at Ten.
