The untold story of post-war Britain. Told through the lives of the two men who helped shape it: Sir David Barclay and Sir Frederick Barclay.

You May Never See Us Again is the only definitive story of David and Frederick Barclay - commonly known as the Barclay brothers. Born poor, these enigmatic twins built one of the biggest fortunes in Britain together from scratch and spent six decades at the epicentre of British business, media and politics. Their empire, said to be worth £7bn at its height, included Littlewoods, the Ritz Hotel, The Daily Telegraph and the channel island of Brecqhou. They were major advocates for Brexit and well-connected with influential politicians including Margaret Thatcher, Boris Johnson and Nigel Farage.

And yet despite their fortune and influence, their fiercely guarded desire for privacy has meant that their story remained largely unknown - until a very public family dispute pitched Barclay against Barclay in the High Court.

Journalist Jane Martinson unravels the fascinating story of these once inseparable billionaire brothers. Through their lives she offers compelling insights into post-war Britain, from the conditions that enabled their way of doing business to thrive through to the tightly enmeshed webs of influence between capitalism, politics and the media that shape Britain today.
