TV tonight: Ant and Dec are back in charge of Saturday night

Ant & Dec’s Saturday Night Takeaway

7pm, ITV

This Saturday night staple was plunged into doubt and controversy when Dec was forced to present the majority of the 2018 series alone after Ant was involved in a car accident. Subsequently, the series was scrapped for 2019. It is a welcome return for the duo now as they begin a new three-year contract with ITV. Personal issues aside, it is hard not to be captivated by the relentless enthusiasm of the pair and their surprise stars. Singer Camila Cabello is the series’ first celeb announcer. Ammar Kalia
