Radio 4 to air one-off 'Torchwood'

A one-off special of Torchwood is being made to air on BBC Radio 4 in the summer.

The 45-minute show is written by Joseph Lidster, who penned a recent television episode and is behind much of the BBC's online Doctor Who content.

Stars including John Barrowman will feature and the Torchwood team will produce along with BBC Wales's Kate McAll.

Airing as Radio 4's Afternoon Play, it has been planned to coincide with the opening of the world's biggest particle accelerator in Switzerland.

Lidster is working the story around a particle accelerator, according to Broadcast.
