C4 Alternative Election Night
9.55pm, Channel 4
We’re here again: another election, another all-night ballot count and malfunctioning set of graphic explainers. Keeping up its tradition as the “alternative election night” to BBC, ITV and Sky’s news-focused coverage, Channel 4 pulls out the zany stops this year, enlisting Rylan Clark-Neal and Katherine Ryan to help Krishnan Guru-Murthy. Even Judge Rinder will be there. Whatever the results, this lot will surely keep us awake. Ammar Kalia

I Give It a Year, 10.30pm, BBC Two
Rose Byrne and Rafe Spall are Nat and Josh, who got married in haste and are now repenting, what with his sweet ex and her rich, handsome American client promising happier-ever-afters. It’s a patchy romcom from Dan Mazer, but with lots of laughs, especially from Olivia Colman. Paul Howlett
