Jonas Armstrong, who plays Robin Hood and updated the popular legend for a whole new generation, is set to bow out of series three on BBC One in an explosive, nail-biting series finale.

The 27 year old is currently filming in Budapest and said: “Over the last three years I have met some wonderful people and have only amazing memories to take with me,” the actor said in a statement.

A BBC spokeswoman said the finale would be “intriguing and guaranteed to make fans desperate to find out what happens next”.

Foz Allen, the show’s executive producer, added: “We cannot confirm the series climax, nor can we guarantee who will survive and who won’t.”
