Athletics: British Championships (BBC1, 1.15pm)

GABBY Logan introduces the second and final day of action from the Manchester Regional Arena, as the best of Britain’s athletes go head-to-head to become domestic champion.

Today’s headliners include experienced pole vaulter Holly Bradshaw, the former European indoor champion, who is bidding for her eighth outdoor national title.

The men’s and women’s 200m finals are also taking place in the city, which is hosting the championships for the first time since 2007.

Other highlights include the final of the women’s triple jump, which features rising star and local favourite Naomi Ogbeta.

The Chase Celebrity Special (STV, 7pm)

IT’S a pretty impressive line-up this week as Bradley Walsh invites celebrity contestants: comedian Jenny Eclair, presenters Ore Oduba and Richard Madeley, and actor Perry Fenwick – better known to soap fans as Billy from EastEnders – to pit their wits against one of the ruthless Chasers in the hope of winning a potential prize pot worth thousands of pounds.

They must work as a team and play strategically to answer general knowledge questions against the clock and race down the game board to the exit without being caught.

Britain’s Got Talent (STV, 8pm)

ANT and Dec host the first semi-final of this year’s talent contest, making a return to screens following the auditions episodes broadcast in the spring.

Amanda Holden, Alesha Dixon, David Walliams and Ashley Banjo are on the judging desk, as the acts that impressed them the most return, including the golden buzzer acts – singer Fayth Ifil, comedian and singer Jon Courtney, choir Sign Along With Us, comedian Nabil Abdulrashid, and mother and daughter singing duo, Honey and Sammy.

Eight acts perform in each semi-final, with two finalists selected by the judges and the votes of viewers.

Piers Morgan’s Life Stories (STV, 10pm)

PIERS Morgan’s chat show often makes for emotional viewing, in part because instead of having a sofa full of celebrities ready to share their favourite anecdotes, each episode is devoted to just one guest.

Now, it’s returning with two episodes that could be the most inspirational and affecting yet. The second edition will feature the nation’s new hero, Captain Sir Tom Moore, while the first marks the return of Vinnie Jones.

He first appeared on Life Stories more than a decade ago and the footballer-turned-actor’s life has changed a lot since then, as last year he lost his wife Tanya at the age of just 53.
