Pippa Middleton's friend to bring some Bunga Bunga to the American Embassy in London Pippa Middleton's chum Charlie Gilkes opened an Italian-themed bar whose name, Bunga Bunga, was inspired by Silvio Berlusconi. Now, the Old Etonian and his business partner, Duncan Stirling, have won a contract to open bars and restaurants near the planned new American embassy in Vauxhall.

We're still at the ideas stage as to what the bars will be like, so we're not near names.

Natalie Pinkham's wedding is just weeks away, but her fiancé, Owain Walbyoff, will struggle to make it to the altar after suffering a serious injury on his stag weekend in Croatia.

Ronnie Biggs: It's a crime As one of the criminals behind the Great Train Robbery, Ronnie Biggs is unlikely to win much public sympathy, but he is concerned about the new ITV drama Mrs Biggs.

I doubt it will be.
