Not only did Rothes possess a famous Covenanting lineage, he was himself a staunch Presbyterian, regularly attending the General Assembly of the Kirk as an elder (and twice in Anne’s reign being mooted as a possible commissioner to the assembly).
Through an entail executed by his mother, who had inherited as countess of Rothes in her own right, John Leslie, barely of age, succeeded to her title on her death in 1700, while his younger brother Thomas took their father’s earldom of Haddington. But in political terms the more significant family connection had been cemented by his marriage three years earlier. It was under the umbrella of the Tweeddale interest that he enlisted in the opposition to the Scottish administration presided over by James Douglas, 2nd duke of Queensberry [S]. He joined Hamilton, Tweeddale and their adherents in seceding from the Scottish Parliament in 1702 in protest at the failure to call fresh elections on the king’s death.
Following the revelations at the end of 1703 about the so-called ‘Scotch Plot’, Rothes was sent with his close allies John Ker, 5th earl (later duke) of Roxburghe [S], and George Baillie‡ to ask the queen for a recall of Parliament in Scotland.
Rothes’s attachment to the Squadrone secured him the prestigious post of lord privy seal (at a salary of £1,000 a year) and a seat on the Scottish Privy Council in the ministerial reconstruction that followed the 1704 session, although at the same time lessening his reputation for integrity and thus weakening his power-base in Fife where he ‘very much lost his esteem and interest amongst the gentry’.
Symbolically, Rothes and his father-in-law travelled to the first session of the Union Parliament in Queensberry’s coach, and once there they duly voted for the ratification of the treaty.
Once the Union had been approved tensions between the Squadrone and the court resurfaced. The first issue concerned the choice of representative peers to the Parliament of Great Britain, which was the subject of negotiations with Queensberry. It was agreed that Rothes was to be included, yet John Lindsay, 19th earl of Crawford [S], was elected in his place, ‘the only difference between the commissioner’s [Queensberry’s] list and that which was carried’. Baillie thought the court guilty of not making ‘their people vote for such of the Squadrone as were in their own list … several of them were suffered to be absent, which made Rothes lose it’. In fact, so convoluted were the voting strategies that Rothes was excluded by accident.
it is entirely their own fault, for none of us failed them but stuck close to the commissioner’s list (where three of them were) except such who were in the list whom they first left out in their nomination … So upon the whole I’m sure the New Party have no reason to blame the commissioner nor the queen’s servants for my Lord Rothes’s disappointment; for not one of them failed them but those whom they failed first.

Rothes had to wait over a year for another opportunity to secure a seat in the Lords. In the meantime he remained in Scotland, pursuing his own and the Squadrone’s political interests there.
Rothes’s next chance to be elected a representative peer came in June 1708. He attended the election and was one of the candidates in the list drawn up jointly by Hamilton and the Squadrone in opposition to Queensberry. Rothes received 50 votes, enough to guarantee his election. At the same time he registered his protest against proxies presented by Queensberry and Seafield in favour of court candidates, on the grounds that neither was eligible to vote, Queensberry because of his recent British peerage (as duke of Dover), and Seafield as a judge of the exchequer.
During his first weeks in the House Rothes watched with interest the first steps taken towards enquiring into the peers’ election. On 20 Nov. 1708 he told Tweeddale that Seafield ‘has found it convenient to lay down the chief baron’s place’, which had been the basis of his protest against Seafield’s right to participate in the election. He also noted with irritation the objections that were being raised by Scottish Members of the Commons against the eldest sons of Scottish peers sitting in the lower House, complaints which he considered ‘very unreasonable’ and the work of ‘the fools of the Parl[iament]’ such as George Lockhart. A fortnight later he wrote that the Commons had ‘incapacitated our sons to be their members which I think is pretty hard upon us, but we are obliged to the 45 Scots for it, for the English would never have made any scruple about it’. His correspondence with Tweeddale also mentioned difficulties between the Squadrone and the Junto. In his view, the Squadrone were ‘not persons that will be led by the nose, and that [the Junto] know, but taking the argument the ordinary way of this world, which is from interest, it would appear that [the Squadrone] and [the Junto] will quickly be at one’. He was present on 11 Dec. at the London home of William Cavendish, 2nd duke of Devonshire, where a meeting was held to resolve differences. Sometime later, on 20 Jan. 1709, he explained to Tweeddale that ‘I think the appearance is better than I have seen it since I came here for there is the greatest probability that we’ll carry our elections and I hope other things shall go well also, but all these things are uncertain till they be done’.
The enquiry into the peers’ election had finally started in earnest and on 10 Jan. 1709. Rothes was named to the Lords’ committee to consider a petition from a number of defeated candidates from the Squadrone’s list. A week later came the report, confirming the number of votes cast for each peer in the election, together with a list of the protests, amongst which were Rothes’s objections against the proxies presented by Queensberry and Seafield. By the 18th Rothes was hopeful that both protests would go ‘very right’.
The recalculation of votes cast in the peers’ election, according to the resolutions of the House, reduced Rothes’s total from 50 to 47, enough for him to retain his seat. He was, however, dissatisfied with other aspects of the proceedings, and suspicious of Godolphin’s intentions.
Having boycotted the peers’ elections in 1710 and 1713, the Squadrone were obliged to oppose the Tory ministry from the sidelines. Rothes kept in close touch with his party colleagues, visiting Roxburghe at Floors Castle in June 1712, from where they went on to a ‘great confluence’ of the Squadrone in Edinburgh.
With the accession of George I the Squadrone (now led by Roxburghe and Montrose) came into their own. In the early days of the new regime Rothes was tipped to become lord clerk register, but in fact his reward was more modest: vice-admiral for Scotland, and commissioner to the General Assembly of the Kirk, a position for which he had been touted previously, and in which he was able to exploit his reputation for personal piety to the government’s advantage.
Rothes died at Leslie House on 9 May 1722, after an illness prolonged enough to enable him to prepare what his deputy-governor at Stirling described as ‘a Christian, sedate and courageous death’. Having ‘recommended religion’ to his children, he summoned his two chaplains and ‘declared the grounds of his faith and hope of salvation’. After a prayer he then died ‘in the greatest serenity and peace’.
