The challenge facing Britain’s Labour and Liberal Democrat parties cannot be overstated. Political parties have no divine right to exist and progressive parties of the centre and centre left are facing marginalisation, even extinction, across the Western world. Where is the French Socialist Party of François Mitterrand or the German SPD of Willy Brandt? And dominant national parties can very quickly become small fringe parties under the hammer blows of poor leadership and social and economic change. Look at the Liberal Party of Asquith and Lloyd George, reduced from 397 to 43 seats in just 18 years in the early 20th century.

Joe Biden’s victory in the United States apart, progressive politics across the globe is badly placed: four election defeats for the British Labour Party and no one betting against a fifth; the German SPD placed behind a moderate Green Party; the French Socialists, who won the presidency in 2012, now polling at 11 per cent; the Italian left imploded and divided; the Spanish and Swedish socialists hanging on to power, but way below their earlier levels of support.
