Lawrence persuaded his brothers that it would be beneficial to deal directly with customers in Lisbon and Oporto rather than through agents based in London and elsewhere in Britain.
[2] The South American enterprise expanded to include offices in many locations but the British government then attempted to impose tariffs on trade there.
[13] Having opposed the imposition of export duties as early as 1815, when the British government had announced its intention to impose a tariff on goods sent to Rio de Janeiro,[14] Heyworth became a supporter of the Anti-Corn Law League.
[16] He was an early supporter of the Complete Suffrage Union (CSU), along with fellow Radicals such as Edward Miall and John Bright.
[17] Although sharing similar aims to Chartism, Heyworth was among those CSU members who were influenced by Joseph Sturge and objected to the methods of Chartist leaders such as Feargus O'Connor.
[18] The influence of Sturge also played a part in his support for the abolition of slavery and his membership of a peace movement called the League of Universal Brotherhood, founded by Elihu Burritt in 1848.
[23] The latter association caused him to visit Wisconsin to promote the organisation's purchase of 1,600 acres (650 ha) of settlement land in the Dane and Iowa counties.
[25][26][27] In 1848 Heyworth was elected to the House of Commons as one of the two MPs for the Derby constituency,[28] a candidacy that owed much to his reformist proclivities and to his position as a director of the Midland Railway, which was based in the town.
