Although Stanley was still under age at the general election of 1685, he could probably have been elected without difficulty for either Preston or Liverpool. But his brother, the 9th Earl of Derby, was determined to establish an interest at Clitheroe in spite of the risk of splitting the Tory vote. With the aid of the local party manager, Roger Kenyon, Stanley was elected, probably without a poll. His only committee in James II’s Parliament was for a naturalization bill.3HMC Kenyon, 178-80.
Stanley had little prospect of succeeding to the title till his nephew’s death in 1700, and was anxious to embark on a military career. His mother was Dutch, and he chose to join one of the English regiments in the United Provinces rather than James II’s army. Presumably he accompanied William of Orange to England in 1688. He was returned unopposed for Preston at the general election of 1689, but again served on only one committee, that for restoring corporations. Though according to Ailesbury’s list he voted to agree with the Lords that the throne was not vacant. William gave him a court appointment and a commission in the guards. He served with distinction in Flanders, while continuously representing Lancashire from 1690 till he became a peer. When present in the Commons he voted as a Whig, but his heart was never in politics. He died on 1 Feb. 1736 and was succeeded by his distant cousin Sir Edward Stanley, 5th Bt..4Draper, 258.
