CATCH -UP TV—IN CASE YOU MISSED IT...

Traitors Channel4.com, until April 24, episodes 1&2 This is set in 1945 with England, fresh out of World War II, about to embark on the protracted menace that was the Cold War.

A surprise landslide victory for Clement Atlee’s Labour party over Churchill’s Tories is an indication of where the country’s politics are leaning, much to the alarm of the UK’s US allies, who want to ensure that England’s ‘socialist’ leaders don’t play into Soviet hands.

Fiona ‘Feef ’ Symonds (Emma Appleton, left) is the well-born daughter of a Tory MP, disappointed that the war is over, and with it her own chances of adventure and excitement. Rather than fall into the route mapped out for her — marriage, children, the endless round of domesticity — she jumps at the chance, proffered by her American boyfriend, to protect her country from ‘hidden enemies’ by working undercover as a spy at the Home Office. Her task is to find a Russian mole, apparently leaking secrets from the very heart of government.

This is written by Bash Doran (Boardwalk Empire), with Keeley Hawes as Priscilla Garrick, terrifying senior civil servant at the Cabinet Office and Luke Treadaway (Ordeal by Innocence), as firebrand young Labour politician Hugh Fenton.

Jump Girls TG4 Player, until March 29, episode 1 Horse racing may be a rare example of a professional sport in which women and men compete directly against each other, and yet this is still an obviously male-dominated industry.

So who are the women who battle it out with the likes of Ruby Walsh and Paul Carberry? And what kinds of lives do they lead, professionally? TG4 here offers a bi-lingual behind-the-scenes look at the particular challenges facing women in horse racing, via revealing interviews with trainer Jessica Harrington and her daughters Kate and Emma, as well as jockeys Rachael Blackmore, Katie Walsh, Lisa O’Neill and Katie O’Farrell.

Directed by Luke McManus, this is beautifully filmed and fascinating.
