Prime numbers

It looks as if Britain will just miss out on having seven prime ministers in the space of a decade as nominations for the Labour leadership election will not open until 9 July (David Cameron left office on 13 July 2016). Have we ever had seven PMs in the space of ten years?

– After Lord Liverpool left office on 9 April 1827 Britain saw a further eight premierships within the following decade. Two, however, saw the same person returning to office, so we had seven different prime ministers within the space of ten years. They were:

Lord Liverpool 1812-27George Canning 1827Lord Goderich 1827-28Duke of Wellington 1828-30, 1834Earl Grey 1830-34Lord Melbourne 1834, 1835-41Robert Peel 1834-35
