National charity Caudwell Children has re-named its annual Butterfly Ball in honour of the Queen’s Jubilee celebrations.

This year's 'Diamond' Butterfly Ball takes place May 31 at Battersea Evolution (see Diary), raising money to help change the lives of sick and disabled children living in the UK. The event will be hosted by West End star Jonathan Wilkes, with a fundraising auction led by former politician and best-selling author Jeffrey Archer.
