DOCTOR WHO: BOOM OVERNIGHT RATINGS REVEALED

Boom stars Ncuti Gatwa and Millie Gibson as The Doctor and Ruby Sunday. Also returning for a cameo in this episode is Susan Twist, playing 'Ambulance'.

Guest cast this episode includes Joe Anderson as John Francis Vater, Majid Mehdizadeh-Valoujerdy as Carson, Caoilinn Springall as Splice Alison Vater and Bhav Joshi as Canterbury James Olliphant.

This weekend's episode saw, caught in the middle of a devastating war on Kastarion 3, the Doctor trapped when he steps on a landmine. Can he save himself and Ruby, plus the entire planet... without moving?

Boom was watched by 2.04m from 6:50pm BST on BBC One in the UK. This figure does not include those who watched on BBC iPlayer in the 18 hours leading up to its BBC One showing, or those who watched on devices.

Compared to last weekend's double bill premiere where Episode 1 (Space Babies) was watched by 2.6m, followed by 2.4m for Episode 2 (The Devil's Chord). Consolidated ratings, which will include iPlayer and all devices, will be revealed early next week.

In the UK, episodes of Doctor Who drop every Saturday at 00:00am on iPlayer and air on BBC One at 6:50pm BST.
