A Staffordshire country gentleman, Mosley had voted with the Whig opposition in his three brief stints in the unreformed Parliament.
upon none of these occasions was he enabled to effect the good which he had eagerly expected as a result of his pursuits, and with the single exception of having been thereby introduced to many talented, and to a few pious men, he found that the rest of his anticipations ended in nothing but vanity and vexation of spirit.
Sir O. Mosley, Family memoirs (1849), 75-6.
The Mosley family owned land in Staffordshire and Lancashire, the latter including the manor of Manchester which they had acquired in the late sixteenth century.
Mosley did not seek a return to Parliament until offering for the new constituency of North Staffordshire at the 1832 general election. A ‘staunch reformer’, he declared support for retrenchment, reform of the church and tithes, a revision of the corn laws and the immediate abolition of slavery.
After the dismissal of Melbourne’s government in November 1834, Mosley was one of a number of Staffordshire Reformers who gravitated towards Peel’s Conservative party. Indeed Josiah Clement Wedgwood, founder of the History of Parliament, has written that ‘this somewhat unknown baronet … tried to form a party of dissident Whigs to support Peel’.
Before the 1836 session, local Conservatives considered forming a tacit alliance with Mosley, which ultimately came to nothing.
At the 1837 general election Mosley declared that he was ‘a Reformer on principle’ but would ‘not aid the work of destruction’.
After protracted negotiations, Mosley sold his manorial rights at Manchester to the town council in 1845 for £250,000, the transfer made by a deed dated 5 May 1846.
On Mosley’s death in 1871, the title, Rolleston Hall estate and personalty of £350,000 passed to his eldest surviving son Sir Tonman Mosley, 3rd baronet (1813-90).
