Cambridge University was a university constituency electing two members to the British House of Commons, from 1603 to 1950. Franchise and method of election This university constituency was created by a Royal Charter of 1603. It was abolished in 1950 by the Representation of the People Act 1948. The constituency was not a geographical area. Its electorate consisted of the graduates of the University of Cambridge. Before 1918 the franchise was restricted to male graduates with a Doctorate or Master of Arts degree. Sedgwick records that there were 377 electors in 1727. For the 1754–1790 period, Namier and Brooke estimated the electorate at about 500. The constituency returned two Members of Parliament. Before 1918 they were elected by plurality-at-large voting, but from 1918 onwards the two members were elected by the Single Transferable Vote method. History In the early 18th century, the electors of both English universities were mostly Tories, but the Whig ministers of King George I were able to persuade him to use his royal prerogative to confer Cambridge doctorates on a large number of Whigs, so that from 1727 the university largely returned Whig representatives. At Oxford, the King did not enjoy the same prerogative power, so that the University of Oxford constituency remained Tory, and indeed often Jacobite, in its preferences. The leading 18th-century Whig politician Thomas Pelham-Holles, 1st Duke of Newcastle, was Chancellor of the University of Cambridge from 1748 to 1768 and recommended to the electors suitable candidates to represent them in Parliament. This practice continued under his successor, another Whig Duke and Prime Minister, Augustus FitzRoy, 3rd Duke of Grafton, Chancellor of the university from 1768 to 1811. However, Grafton was less influential as a politician than Newcastle had been and also less attentive towards the university, and as a result some of his nominations came in for criticism, notably that of his friend Richard Croftes. Croftes was far from typical of a university member of parliament: he was neither the son of a peer, like the Hon. John Townshend, the Marquess of Granby, and Grafton's own son the Earl of Euston, nor a distinguished lawyer-politician, such as William de Grey, James Mansfield, and Sir Vicary Gibbs, nor a prominent political figure like William Pitt the Younger and Lord Henry Petty. In the late 18th and early 19th centuries, Pittite and Tory candidates began to be elected. At the appearance of this political
