A lightsaber used by Darth Vader in the original Star Wars films has gone on display in London ahead of an auction where it is expected to sell for millions.

The primary duelling lightsaber, featured in the climactic battles in The Empire Strikes Back (1980) and Return Of The Jedi (1983), could fetch up to three million dollars (£2.2 million).
