A beachcomber who pocketed part of a haul of a cocaine worth £50million which he found on his local beach is facing jail.

Drug user Julian Underhill, 34, sent a text message describing his find as like stumbling across "Willy Wonka's golden ticket".

Norwich Crown Court heard how 356kgs of the Class A drug were washed up last February at Hopton, Hemsby and Caister-on-Sea near Great Yarmouth, Norfolk.
