The BBC finally confirmed he was leaving in June - but remained tight-lipped on who would be the replacement.

The BBC will reveal their identity during a live BBC One show at 7pm tonight - or if you really can't wait, here's the trailer.

Zoe Ball will unveil the Doc in front of a live studio audience set against the backdrop of a swirling vortex and amongst Daleks.
