The Voice UK Final (STV 8.40pm)

The last four acts compete for the chance to win a recording contract and be crowned this year’s winner. They are Jonny Brooks, 28, from Ireland; Gevanni Hutton, 17-year-old student from London; Brooke Scullion, 20, from Derry in Northern Ireland; and Blessing Chitapa, 17, from Dudley in the West Midlands.

For the first time, the winner of this year's contest won't be decided by viewers at home, but instead by a virtual audience. It’s coach Meghan Trainor’s final show as she is stepping down ahead of the next series, for which auditions are already under way.

Strictly Come Dancing (BBC1, 7.10pm)

HRVY and Maisie Smith appear to be the celebs to beat this year. However, if previous Strictly series are anything to go by, there could be an unexpected contender who comes up on the rails, so the pair won’t be taking anything for granted in their quest to win the Glitterball trophy. Tess Daly and Claudia Winkleman host the fourth live show tonight, as the 10 remaining couples take to the floor in a bid to impress judges Shirley Ballas, Craig Revel Horwood and Motsi Mabuse, as well as viewers at home. The two couples with the lowest combined scores from the judges and public votes will then dance off for survival tomorrow.

Lord Mountbatten: Hero or Villain? (C5, 8.40pm)

HE was the war hero who led Allied efforts in southeast Asia, the statesman who was so admired as last viceroy of India that he was invited to be its first governor-general, and the family man who Prince Charles described as “the grandfather I never had”.

But what is the truth that lay behind Lord Louis Mountbatten’s golden reputation? This documentary looks at the life of the Queen’s second cousin who was killed in August 1979 when the IRA detonated a bomb on his family’s fishing boat in north west Ireland.

David Crosby: Remember My Name (Sky Arts, 9pm)

THIS deeply personal documentary explores the life and creative renaissance of the music icon. A cultural force for over 50 years, Byrds founder member Crosby faced an uncertain future after the 2015 dissolution of Crosby, Stills & Nash. Racked with health issues and personal obstacles, he forged a new path at the age of 77.

Seeking out younger musicians and recording a pair of new albums, he set out to make a mark in a world so different from the generation he came to define in the 1960s. With unflinching honesty and an unshakable belief in family and the transformative nature of music, Crosby shares his often-challenging journey.
