A distinguished barrister, Thomas Headlam entered parliament as an ‘independent Liberal’ in 1847 and became a ‘persistent’ reformer of ‘land and company law’.
Connected to Newcastle by his uncle, Dr Thomas Headlam, a Liberal alderman of the city who had served twice as mayor, Headlam was returned in 1847 following a requisition from local advanced Liberals. A frequent speaker in his early parliamentary career, Headlam displayed a willingness for reform by intervening on a number of legal matters,
After being consistently supportive of Lord John Russell’s ministry, Headlam, who comfortably defended his seat in 1852, voted for censure of Aberdeen’s ministry, 29 Jan. 1855, and was often critical of Palmerston during his first administration. In February 1856 he opposed the premier over the local dues and shipping bill, and later openly attacked him for not honouring his promise concerning the commissions of deceased army officers.
Headlam’s opposition to Palmerston reached its peak on 5 May 1858 when, after voting against his conspiracy to murder bill, 19 Feb. 1858, he presided over a meeting of 120 MPs who, styling themselves the ‘independent Liberal party’, expressed their dissatisfaction ‘with the manner in which their opinions had been represented by the last Government’. Headlam went on to stress that, given their apprehensions, they would not support any government unless ‘they were prepared to energetically reform our administrative departments (as, for instance the War-office and the Foreign-office), and in other respects carry out the views of the Liberal party’. Headlam also called for some ‘independent organization’, and the meeting concluded with a number of resolutions endorsing the points he had raised.
Headlam’s role as judge advocate-general was thrust into the public eye in November 1863, when the government ordered the court martial, in England, of Colonel Crawley, who had commanded the 6th Dragoons in India. In 1862, at Mhow, Crawley had controversially acted as prosecutor in the court martial of one of his soldiers who had criticised his style of leadership, a process Headlam felt was ‘objectionable’ but not ‘illegal’.
Lauding the leadership of Palmerston, Headlam retained his seat at the 1865 general election, although he had been forced to defend himself against the accusation that, as judge-advocate general, he seldom visited Newcastle, and had lost touch with his constituents.
After promising to faithfully follow Gladstone, Headlam was once again returned for Newcastle in 1868. He was not, however, offered his former post, prompting Headlam to complain to Gladstone that the decision ‘had taken place without a word written or spoken to me,’ which ‘was not the treatment to which one like myself should be subjected, who had fought many contested elections in Newcastle on Tyne, and who had worked for the Liberal party as I did at the last election both in my own and neighbouring constituencies’.
