The heir of a famous Victorian entrepreneur, Jackson was a barrister and a ‘man of great legal learning’.
Jackson’s father William Jackson (1805-76) was a ‘hard-headed, self-made man’.
After serving as a barrister on the north Wales circuit and in the Palatine court in Lancashire, Jackson moved to London, where ‘for many years he was one of the leaders of the Chancery bar, enjoying a large and lucrative practice’.
Jackson stood as a Liberal candidate for Birkenhead at the 1865 general election, when he advocated enfranchising a greater proportion of working men to stabilise the political system.
However, Jackson had impressed Liberals in Coventry, where he was brought forward at the 1867 by-election after local candidates declined. In his speeches, Jackson argued that the Liberal party was the sole originator of progressive measures. Speaking of the representation of the people bill, Jackson contended that ‘it was not to Disraeli, but to Gladstone and Bright, backed as they were by the great Liberal party, that the country was indebted for all that was really liberal in this bill’.
Although his experience at the bar made Jackson a ‘fluent and effective speaker’ he made no speeches during his first spell in the Commons.
Jackson was defeated for Coventry at the 1868 general election. He took silk in 1873 and was returned for Coventry in 1874 and re-elected in 1880. On his father’s death in 1876, he inherited the baronetcy and the Llantilio Court estate in Monmouthshire, comprising 3,137 acres with an annual rental of £4,200.
In early 1881, having long suffered from gallstones, Jackson was afflicted with a ‘cold and liver complaint, complicated by other affectations’.
