New Channel 4 show Lego Masters is aiming to find great Lego builders, while Ambulance returns to BBC One to profile a British midlands hospital

Pick of the day

Lego Masters, 8.00pm, Channel 4

The hunt is on for the UK and Ireland's best Lego builders, as some of the two countrys' most skilled brick fanatics do battle to be crowned Lego Master.

In the first episode, 48 pairs are whittled down to just eight final teams through a series of challenges. Next, the eight teams must create a spectacular brick banquet, including an impressive chair that not only looks the part, but also strong enough for presenter Melvin Odoom.

The teams must also make at least one supersized masterpiece for the banquet table. The results include a crispy aromatic duck and prawn toast, a hog roast, and a gravity-defying cup of tea.
