Sir Philip Green’s US venture has been given a welcome boost as Prime Minister Gordon Brown’s wife gave Barack Obama’s daughters gifts from Topshop.

Sarah Brown personally gave gifts from the high street chain to the President’s daughters Malia and Sasha. The Prime Minister's wife is understood to be a fan of Topshop, having recently worn a£7 beret to an official engagement with her husband.

Green told The Daily Telegraph he was unaware that the gifts were going to be presented to Obama’s children but was delighted. “We are both excited and delighted that Mrs Brown chose Topshop on her first trip to Washington. What an excellent present,” he said.

Green said Obama’s family could even become regular shoppers, as Topshop is due to open in the US next month. “We hope the Obamas will be customers of ours,” he said.
