The Royal Navy's latest submarine, HMS Artful, will be officially commissioned at a ceremony on Friday.

It will take place at Faslane naval base on the Clyde, with representatives of the Royal Navy and the companies that built the vessel present.

Guest of honour at the ceremony will be the submarine's sponsor Lady Amanda Zambellas, who named the vessel during its launch in 2014.

The 7400-tonne attack submarine is powered by a nuclear reactor and is the third vessel in the Astute class.

It boasts state-of-the-art communications equipment and advanced stealth technology.

The other submarines in the class, which are in various stages of design or build, are Audacious, Anson and Agamemnon. The seventh boat name has still to be confirmed.

Faslane will host all seven vessels and is already home to HMS Astute and HMS Ambush.
