Spectacular Spain with Alex Polizzi

Channel 5, 9pm

Alex arrives in the popular holiday region of Andalucia and begins her exploration at the Tabernas desert in Almeria, a striking and unusual part of Spain has featured in countless spaghetti westerns. She then moves further west to the green and fertile mountains of La Alpujarra in the foothills of the Sierra Nevada mountain range, a region famous for its tranquil retreats and alleged healing waters.

Decline and Fall

BBC1, 9pm

Wide-eyed innocent Paul Pennyfeather is in Marseille at the behest of his beloved fiancée, Margot Beste-Chetwynde. Some of her “girls” are caught up in bureaucratic red tape and Paul is just the chap to sort it out.

As this fairly lifeless adaptation of Evelyn Waugh’s brilliant comic novel comes to a close, Paul (Jack Whitehall) falls head-first into a massive mess. He’s a naif, bribing bad men without thought, and he gets into trouble. Meanwhile, back home the lovely Margot (Eva Longoria) is preparing for the biggest of all society weddings. 

Brace yourselves for a shocking bit of gore, and the line “I love you, but I’m worried that you’re sleeping with the Home Secretary”.

Spin

More 4, 9pm

The taut, pacey French political thriller returns for a third and final series, and this breathless opener suggests it’ll be a savage race in the final six months before the presidential elections. As things stand, the extreme far-right party is leading the opinion polls – but a bloody assassination alters the political landscape and sends those at all ends of the spectrum into stunned turmoil.

President Marjorie is under pressure to at least attempt to ensure things run smoothly during his final months in the Elysée, but his strained relationship with his wife is a further distraction - while his spin doctor Simon Kapita is at loggerheads with his former protégé Ludovic, who’s backing a radical candidate from the Right. Fantastic.

Selma

BBC2, 9pm

Director Ava DuVernay's sweepingly staged, dogmatic history lesson avoids the episodic pitfalls of the biopic by eschewing Dr Martin Luther King's whole life story in favour of a single flashpoint. She focuses on the three marches led by the civil rights beacon in 1965 from Selma in Alabama to the state capital, Montgomery, demanding equal voting rights for blacks. British actor David Oyelowo gives a career-defining performance as Dr King: stirring and full-blooded in public oratory from government steps to pulpit, fallible in private, but a match for Democratic President Lyndon B Johnson (Tom Wilkinson, whose amplified turn conveys sympathy within intransigence). There is an epic feel to the massed scenes on Edmund Pettus Bridge, but most of the action takes place indoors, where DuVernay gets the most out of a huge cast in smaller parts (including producer Oprah Winfrey, rapper Common and an uncredited Martin Sheen). If Tim Roth's segregationist governor George Wallace tips into panto and the concluding montage of news photos risks over-egging the message, the overall sense of righteous, non-violent anger is palpable.
