We are Most Amused and Amazed, STV, 8pm

PRINCE Charles turns 70 tomorrow, which is a pretty good excuse for a party. So the London Palladium is hosting a spectacular night of comedy and magic, which will celebrate the landmark birthday and raise funds for the youth charity The Prince’s Trust. On-off double act Alexander Armstrong and Ben Miller are reuniting to host the event, and more comedy is provided by Bill Bailey, Rowan Atkinson, Sandi Toksvig, Omid Djalili, Mischief Theatre and Alistair McGowan, while the magic comes from Dynamo, Penn & Teller and The Ehrlich Brothers. There are also appearances from actor Jim Carter, singer Cheryl, honorary national treasure Kylie Minogue and, perhaps most surprisingly of all, Wallace & Gromit.

Informer, BBC1, 9pm

ONE of the most hyped BBC dramas of the year reaches its penultimate edition and Raza and Gabe’s relationship is severely tested as the case takes a fatal turn. Holly’s curiosity reveals the truth about Gabe’s undercover past and her probing unwittingly leads to his two worlds colliding. Increasingly on edge, Raza reacts aggressively to Akash’s growing influence on Nasir, while his family are caught up in the maelstrom of his double life. Paddy Considine, Bel Powley and Nabhaan Rizwan head the cast.

Dan Cruickshank’s Monuments of Remembrance, BBC4, 9pm

AT the end of the First World War, Britain faced a difficult question: How could it pay a fitting and lasting tribute to the unprecedented number of soldiers who had died? Here, Dan Cruickshank explores the creation of the Commonwealth War Graves Commission and the role played by Sir Fabian Ware, who, as a commander of a mobile ambulance unit during the early stages of the war, had been shocked by the treatment of the dead. The presenter also visits cemeteries in France, Belgium and Turkey to discover the challenges in memorialising soldiers from different religions and backgrounds.
