Leedes’s first known ancestor held Wappingthorne, in west Sussex, in the early fifteenth century and sat for Sussex in 1432. Leedes’s grandfather was a Catholic and spent much of his life in exile or under confinement.
As the eldest son, Leedes was left to take over the family estate, consisting of property in Sussex and Yorkshire, out of which he provided for the upkeep of the exiles. He showed no trace of Catholic sympathies, and by this date seems to have been in attendance on the king, possibly acting as deputy for his father-in-law, Sir Thomas Monson, a gentleman usher of the privy chamber, a post that Leedes himself would hold.
Leedes first entered Parliament in 1614, when he served for the nearby borough of Bramber. He owned property there, but he probably also enjoyed the support of the Howards, who owned the borough and were Monson’s patrons. He left no mark on the records of the Addled Parliament. In the following spring he played some part in Court intrigue against the rising George Villiers, for his father, still in close touch with English affairs, wrote to William Trumbull in April 1615 stating that he wished him ‘a less meddler in factious business’.
Leedes seems to have been restored to favour by 1617, when he attended the king in Scotland, and two years later he helped to support the canopy at the funeral of Anne of Denmark.
Leedes was returned for New Shoreham to the third Jacobean Parliament together with Sir John Morley, the brother of another of his trustees, Edward Morley*. However, he omitted to take the oaths of supremacy and allegiance at the start of the session, a requirement of membership, even though he sat for a quarter of an hour in the chamber in the morning on 7 February. Two days later Sir Thomas Roe, fearing some had evaded the requirement to take the necessary oaths in the confusion of the start of the session, moved for an investigation to establish who had been sworn. Consequently, the following day the House was called and each Member was required to ‘protest concerning his taking the oaths’. Leedes, realizing that he could not honestly make the protestation, went to Sir George More, who had been one of the commissioners deputed by the lord steward to administer the oaths. He offered to take the oaths, but admitted to More that he had already sat in the chamber, whereupon More refused to swear him. More reported the case to the Commons, which ordered that Leedes should be disabled. Sir Edward Sackville, another of his trustees, was prepared to excuse him; but the House debated at some length the question of further punishment. It was urged that his father was ‘a fugitive’ and that as a former Member he could hardly plead ignorance. But he was able to show not only that he had taken the oaths as the king’s servant but also ‘that he had twice received the communion within the compass of that year’, and he was allowed to depart unscathed.
In July 1621 Leedes was one of those arrested along with the 18th earl of Oxford for discussing the Spanish Match. He was probably soon released, but may have lost his position at Court.
Leedes received permission to travel abroad in 1631, possibly in order to attend the funeral of his father, who had obtained permission to be buried in a Jesuit church, although the date of his father’s death is unknown.
