The twin daughters of President George W. Bush have written an open letter to Malia and Sasha Obama, offering advice as they join "another rarified club, one of former First Children".

It was Barbara Bush and Jenna Bush Hager who first showed Barack Obama's children round the White House in November 2008.

Aged 10 and seven years old respectively, Malia and Sasha concluded the visit by jumping up and down on the beds and sliding down the banisters.
