A collection of Marilyn Monroe memorabilia worth around $16 million (£10 million) is to be auctioned for charity.

A British collector has spent his life amassing rare items, including the late actress' dresses and underwear, and he now plans to sell his hoard this summer (14) to raise money for good causes and mark what would have been Monroe's 90th birthday on 1 June (15).

Seller David Gainsborough Roberts tells Bbc.co.uk, "I have been collecting for many years, I'm 70 years of age now, I don't have a wife and children so I thought I must sell things... I have got a lot of big things out there which I hope people will love and buy."

Avid collector Roberts will also be selling off other memorabilia relating to former British Prime Minister Winston Churchill and Nazi dictator Adolf Hitler.
