What to watch tonight - Birds of a Feather returns after 15 years

Uppity neighbour Dorian returns in the guise of the next EL James

Birds Of A Feather

8.30pm, ITV

One of the most popular BBC sitcoms of the Nineties now transfers to ITV for a comeback series – not totally out of the blue since leading actresses Pauline Quirke, Lesley Joseph and Linda Robson starred in Marks and Gran’s successful recent stage show of the same. Sharon’s living back in her council flat and Tracey’s still in Chigwell with son Travis (played by Quirke’s real-life son Charlie), while Dorian has re-named herself Foxy and become an author of “mummy porn”.

Dolphins – Spy In The Pod

8pm, BBC1

We’ve spied on penguins and polar bears, now it’s the turn of dolphins to get the hidden-camera treatment as camcorders attached to fast-moving submersibles record life in the oceans. The man-made “spies” swim alongside bottlenoses and a megapod of spinner dolphins, filming behaviour rarely seen before, such as a newborn and his mother hunting kingfish.

Silent Witness

9pm, BBC1

Richard Lintern joins the cast as a forensic pathologist and the new boss of Nikki (Emilia Fox) and the team. The first double episode involves the unsolved cases of a wealthy mother and son murdered in their home and the disfigured body of a young woman.

PQ17: An Arctic Convoy Disaster

9pm, BBC2

Say what you like about Jeremy Clarkson, he can be a first-rate journalist – and here a historian with a Max Hastings-like grasp of the telling detail. Paying tribute to British and US sailors – many of them ill-paid merchant seamen – who manned the Second World War Arctic convoys, Clarkson focuses on the disastrous convoy PQ17. Scattered on ill-considered orders, it was picked off by German planes and submarines – “a bleak, horrible, awful day” (according to one survivor), mitigated by acts of heroism.
