PICK OF THE DAY

MASTERCHEF 8PM, BBC1

★★★★

This is it then, the final episode of this year’s series as the 20th winner is crowned. There’s just one challenge standing between the final three chefs and a place in the Masterchef Hall of Fame. All they have to do is deliver a flawless three-course menu that will tantalise the taste buds of judges John Torode and Gregg Wallace. So, who can stand the heat of the kitchen and emerge victorious?

LOCATION, LOCATION, LOCATION 8PM, CH4 ★★★

Kirstie Allsopp and Phil Spencer are in south London this week, searching for a flat for first-time buyers Adam and Nicole. They’ve saved for their entire adult lives to get a large enough deposit, and are understandably nervous about spending all that hard-saved cash. Meanwhile, the property experts are also looking for a townhouse for world-record-holding rower Kat. But even though she has a budget of over a million pounds, Phil finds it tough to hit everything on her wish list.

SECRETS AND SPIES: A NUCLEAR GAME 9PM, BBC2

★★★★ It’s 1985 in the final instalment of this gripping tale, and Mikhail Gorbachev is the new leader of the Soviet Union at a very tense time. Margaret Thatcher and Ronald Reagan are hoping that fresh leadership in the Kremlin will offer an opportunity for constructive dialogue. Pivotal to these negotiations is top double agent Oleg Gordievsky, whose story is told here through testimony from former KGB, CIA, FBI and MI6 officers, and audio interviews with Gordievsky himself.

CASUALTY 24/7: EVERY SECOND COUNTS 9PM, CH5

It’s a bank holiday weekend, and the team at Barnsley casualty are bracing themselves for a chaotic day, particularly with the local football team playing a key match. Among the patients waiting to be seen are a dog-walker with a gashed head, a car crash victim with a badly broken leg, a motocross rider with an injured hand and a little boy with severe sunburn.

It takes all sorts...

INSIDE NO. 9 10PM, BBC2 ★★★★

This latest ingenious tale of the unexpected from Steve Pemberton and Reece Shearsmith is seen entirely through a couple’s doorbell camera. A new couple (Shearsmith and Vinette Robinson) move into 9 Mulberry Close, but after strange noises are heard coming from the house, the neighbours (played by Pemberton, Dorothy Atkinson and Adrian Scarborough, left) decide to investigate – but get much more than they bargained for.
