Although he was born in Kenilworth, Warwickshire, Johnson’s family roots lay in Lincolnshire, where his grandfather, Rev. Woolsey Johnson, inherited land at Witham-on-the-Hill, building a manor house, and enclosing the park in 1752.
Johnson first attempted to enter the Commons in 1820, as an anti-corporation candidate at Boston. Although unsuccessful, he was seated on petition. In a Commons speech, 21 Apr. 1823, he ‘avowed himself a radical, however unpalatable the term might be in that House’, and was usually found voting with the Whigs against Lord Liverpool’s ministry, and in favour of retrenchment, Catholic relief and parliamentary reform.
Johnson’s ‘known attachment to the principles of Mr. Cobbett’, viewed by Robert Heron as a liability, was to prove a considerable asset in securing his nomination as candidate for Oldham in 1837.
Johnson appeared alongside Fielden to give accounts to their constituents in 1839, September 1840 (Fielden also appeared in January, when Johnson was absent due to illness), 1841 and 1843, with Johnson noting that his votes in the House had seldom differed from his colleague.
When Johnson was present, he was often found voting against Whig ministers, for example, on a select committee to inquire into punishments in the army, 26 Mar. 1838, and on slave apprenticeships, 28 May 1838, although he supported them on Peel’s amendment to the Government of Ireland bill 1839.
Among the popular causes espoused by Johnson was electoral reform. Supporting Hume’s motion on household suffrage, 21 Mar. 1839, he claimed that ‘he was the first who, several years ago, declared himself in that House in favour of universal suffrage’.
Speaking in support of Villiers’ amendment for immediate abolition of the corn laws, 24 Feb. 1842, Johnson noted that his vote here would be ‘completely against his own interest, as his sole dependence was on land’.
The issue on which Johnson spoke most frequently, however, was the poor law. Just as Fielden encouraged resistance to its implementation in the North, Johnson as a Lincolnshire magistrate had ‘declined every act… towards carrying it into execution’.
Outside Parliament, Johnson took an interest in the development of railways in Lincolnshire in 1845, and later served as a director of the Bourne and Essendine railway, founded in 1856.
Johnson did not take an active part in politics following his retirement in 1847, instead devoting himself to his Lincolnshire estates. He served for 32 years as chairman of the Kesteven bench, and was ‘perhaps the ablest and most progressive magistrate of his day in Lincolnshire’.
