Another rare opportunity to ascend the BT Tower is coming up shortly. It's a charity event in aid of Freedom From Torture, an organisation that helps those who have suffered from torture.
The event takes place on 8 August, marking 20 years since John McCarthy was released from captivity in Lebanon after spending nearly five years as a hostage. Tickets cost £30, every penny of which goes towards the charity's work. You can book your visit here, and find out more on the charity's Facebook page.
UPDATE: THIS EVENT IS NOW SOLD OUT
