Johnson, who came from an old Lincolnshire family, well established as a clerical dynasty by the mid-eighteenth century, was a descendant of Archdeacon Robert Johnson, the Puritan divine and founder of the grammar schools at Oakham and Uppingham. His grandfather held a number of livings, including the vicarage of Witham-on-the-Hill, where he built the manor house and enclosed the park in 1752. His uncle George William Johnson inherited Witham and was sheriff of Lincolnshire, 1784-5, and his father held livings in Staffordshire and Shropshire.
At the 1820 general election Johnson accepted an invitation to stand for Boston on the Blue or anti-corporation interest, following the unexpected retirement of William Alexander Madocks*. According to Drakard’s Stamford News, a more ‘upright, zealous and really independent’ man could not have been selected. He declared his ‘rigid regard’ for economy and the freemen’s independence, but was defeated after a two-day poll. He appeared on the hustings at the county election in company with his friend Sir Robert Heron* and, according to a correspondent of the Stamford News, his future success at Boston was certain.
Johnson took his seat, 28 Feb. 1821, and, according to the Stamford News, gave his first vote in favour of Catholic relief that day, though he does not appear in the known division lists. He divided in the same sense, 1 Mar., 21 Apr. 1825. A frequent attender, he voted with the Whig opposition to the Liverpool ministry on most major issues, including economy, retrenchment and reduced taxation.
Johnson presented a private petition against Catholic claims, 19 Apr. 1825, when he said that were he a Catholic, he could not take the oath as enjoined by the proposed relief bill. He spoke and voted against the accompanying Irish franchise bill, which he condemned as a ‘wanton destruction of popular rights’, 26 Apr., was a minority teller against it, 9 May, and next day told the House that he was familiar with Irish elections and did not think emancipation ‘worth the price of this bill’. He spoke and was a minority teller against the ‘unexplained augmentation’ of the army, 7 Mar. On 11 Mar. he objected to the ‘inequality’ of military punishments, noting that there were regiments in which 100 lashes were the equivalent to 300 inflicted in others. He presented two petitions from Lincolnshire against revision of the corn laws, 28 Apr. 1825, when his proposed adjournment of the debate was lost and the House divided on Whitmore’s proposal for inquiry.
At the 1826 general election he duly retired from Boston and offered for the county. Without the support of Thorold and Heron, who had unsuccessfully tried to rescind the resolution by which he had been adopted, his chances were bleak and he soon desisted, citing the divisions among the independents. According to Heron, who still valued him as a friend, he had become particularly unpopular by following the opinions of Cobbett. Johnson accepted Chaplin, the senior county Member, as the ‘legitimate’ Tory, but again denounced Amcotts Ingilby as a Yarborough nominee. He renewed his attack on the hustings, after a long and detailed speech on the economy, and declared the ballot to be the only way to stop coercion. He boasted of his own attempt to uphold the county’s independence in 1823 and stigmatized the Whigs as ‘old hacks’ for carrying Amcotts Ingilby’s election.
Shortly after the completion of his shrievalty Johnson announced his candidature for the Southern division of Lincolnshire in a reformed Parliament. He favoured the correction of ‘all abuses’, but was reluctant to engage in a personal canvass. He sought the support of Heathcote, already encouraged by Heron to stand, but met with a polite rebuff. He withdrew his candidature, pending the division of the county, after Yarborough’s son signified his intention of standing.
At the 1832 general election he was brought forward for North Leicestershire by Paget, in an abortive bid to resist Rutland’s influence. In defeat he denounced the coercion of the gentry and clergy and spoke of the ‘crying necessity’ for the ballot. At the nomination of his friend Captain Joseph Wood, the unsuccessful radical candidate for Huddersfield, he argued the case for cheap government and further reform.
