'Doctor Who' scripts leak to tabloid

Spoilers for two new episodes of BBC show Doctor Who have been leaked to The Sun.

The paper claims to have received scripts for episodes nine and ten of the new series, with BBC chiefs "fuming" over the leak.

An insider revealed that producers had been desperate to keep the show's secrets under wraps, saying: "Bosses are fuming - this is the last thing they would want to happen."

The episodes comprise a double bill due to air on BBC One in early summer and sees the Doctor and sidekick Donna Noble (Catherine Tate) travel to the 51st Century.

The pair are said to arrive at a giant library that contains books about people's life stories, dead bodies and the Vashta Nerada, "piranhas of the air - shadows that melt the flesh".

Former ER actress Alex Kingston also appears in the special as an astronaut-archaeologist called Professor River Song.
