10-year-old wins Blue Peter Jubilee design competition

A 10-year-old girl has won a competition to design the Queen's official 2012 Diamond Jubilee emblem.

Katherine Dewar, from Chester, was chosen from 35,000 entries in a nationwide competition run by BBC children's programme Blue Peter.

The design - which has a crown poised above the Union Jack alongside columns of diamonds - will appear on everything from posters to commemorative tea cups.
