A World War II era submarine undergoing a £7m makeover has had its newly restored hull unveiled.

HMS Alliance, which is the UK's last surviving submarine from the war, is based at the Submarine Museum in Gosport, Hampshire.

Sailors who served on the ship were in attendance to see the results of the restoration work.

Work will now start on the inside of the 69-year-old vessel.
