[1] Ingham took to law and was admitted to Lincoln's Inn on 16 June 1820, moving to the Inner Temple in 1825.
He returned as a member of parliament (MP) for South Shields in the election of 1832, initially as a Tory.
He continued to represent South Shields until he was defeated by John Twizell Wawn in the election of 1841.
When Wawn retired in 1852, Ingham beat Henry Liddell in the 1852 election to regain his seat, this time as a Whig.
Ingham resigned his attorney-generalship in 1861, and served as reader of the Inner Temple in 1862 and treasurer in 1863.
