In Ten Years to Save the West, Truss, who as Prime Minister sought to champion limited government and individual freedom, will argue that the rise of authoritarianism around the world and the adoption of fashionable ideas propagated by the global left give us barely a decade to preserve the economic and cultural freedom and institutions that the West holds so dear.

Peppered with newsworthy anecdotes from Truss's time in public life - such as her memorable last meeting with Queen Elizabeth II, her challenges to Vladimir Putin and Xi Jinping as Foreign Secretary, her encounters with the Trump administration as Trade Secretary, and her dismay at the political class's attempt to betray Brexit - Ten Years to Save the West will also offer a timely warning about the perils facing conservatism in the years ahead.

In it, Truss will warn that too many of her fellow conservatives have allowed themselves to be captured by the left-wing influences that set the agenda and frame the debate in so many institutions from the media to academia and the corporate world.

She will also call for a return to the alliances built by leaders such as Reagan, Thatcher and others in another era when Western values were under siege. Only if the West recommits to building both strong societies and strong economies, unhampered by big government and regulation, Truss argues, can we guarantee voters a free and meaningful choice in their destiny.
