Sir David Rowat Barclay and Sir Frederick Hugh Barclay (both born 27 October 1934), commonly referred to as the "Barclay Brothers", are British businessmen. The identical twin brothers have very substantial business interests primarily in media, retail and property. The Sunday Times Rich List of 2015 estimated their wealth at £6.5 billion. They have earned a reputation for avoiding publicity, and are often described as reclusive. In 1993 the brothers bought the lease of the island of Brecqhou, off the coast of Sark, one of the smallest of the British Channel Islands.
