Six months after Chelsea Clinton married investment banker Marc Mezvinsky, the granddaughter of President’s George HW Bush has announced she is to marry another New Yorker of Jewish descent.

Lauren Bush, niece of George W Bush, is engaged to the son of Jewish fashion designer Ralph Lauren.

At 39 David Lauren, the executive vice-president at Polo Ralph Lauren, is 13 years older than his future bride. The couple met in 2004.

Ms Bush, a designer and former model, will become Lauren Lauren when the couple marry next year. However she is not expected to take on Ralph Lauren's original name - Ralph Rueben Lifshitz.
