Born into a military family at Bamburgh in 1796 Watson was, upon his father’s death on service in November 1811 ‘left an orphan in the establishment at Sandhurst’, entering the army aged 15.
Whilst on the Northern circuit he acquired a reputation as a popular and dependable advocate, distinguished ‘by his hearty and forcible style of address’.
Watson was outspoken about what he considered illiberal or repressive legislation. A stern critic of the Irish arms bill of 1843 which, he told the House, placed ‘8,000,000 of their fellow citizens beyond the pale of the constitution’, he argued that concession was the only means of undercutting the repeal movement. In May 1846, he warned the House against the advisability of proceeding criminally against William Smith O’Brien for refusing to serve on a select committee.
Though a ‘sincere Protestant’ and a member of ‘the low-church-party’, in 1843 Watson became involved in the movement to repeal the remaining ‘penal laws’ affecting Roman Catholics, which he described to the House as ‘a deep stain on our Statute book’.
Although Watson spoke on behalf of Kinsale’s fishing industry in 1847, arguing that railway access to markets might increase revenues by more than a factor of ten, and drew attention to the overcrowding of Kinsale’s workhouse during the debate on the Irish poor relief bill.
In July 1852 Watson contested Newcastle-upon-Tyne, after a feud between Liberal factions on the town council over the selection of a second candidate led to his nomination. Advocating religious freedom and the abolition of the income tax, Watson directed his opposition towards the sitting member, Thomas Headlam. Yet while his independent stance and inconsistent record of support for Russell’s administration garnered him a large number of Conservative votes, his failure to attract Liberal support left him at the bottom of the poll.
By now Watson was regarded as ‘a staunch Liberal’, who was in favour of parliamentary reform, the admission of Jews to parliament and national education.
During his time in parliament, Watson’s legal career had flourished. Having been made a QC and bencher of Lincoln’s Inn in 1843, he vacated his seat when he was appointed as baron of exchequer on 5 November 1856.
