Titanic: The New Evidence
Channel 4, Saturday, 8pm
Another chance to see Senan Molony's investigation of why White Star Line's Belfast-built ship sank on its maiden voyage.

A Very English Scandal
BBC One, Sunday, 9pm
In the late 1960s the leader of the British Liberal Party, Jeremy Thorpe, was a politician with a brilliant career and a bright future. But he had a dark secret, and he went to extraordinary lengths to prevent it from coming out. At a time when homosexuality was still illegal, Thorpe had an affair with a young stablehand, Norman Scott. With his political star on the rise, Thorpe knew it would be the end of his career if the liaison were made public, so he set out to silence his ex-lover for good. This three-part drama tells the shocking story of corruption, deceit and conspiracy to commit murder. Hugh Grant stars as Thorpe, with Ben Whishaw as Scott. The story is written by the Bafta winner Russell T Davies and directed by Stephen Frears, so with all those starry names on the bill we're expecting some seriously good telly.
