Derry Girls

Channel 4, 9pm

The gags arrive thick and fast as Lisa Mcgee’s awardwinning Northern Irish sitcom continues its victory lap. A seaside trip becomes an away-day from hell for the Quinns, when a former friend buttonholes them en route (in a very funny cameo by Sinéad Keenan, new star of cop drama Unforgotten), and the gang wind up with a rucksack full of contraband.
