Gwyn successfully contested Penryn and Falmouth at the 1847 General Election and continued to represent the borough until 1857. He represented Brecon from 1866 until 1869 when he was unseated by petition. Having been returned for Brecon in 1868 it was generally accepted that his supporters had been caught engaged in bribery. The following year, a petition was brought forward to unseat him due to allegations of bribery and illegal activities. Gwyn was largely exonerated personally but the charges were upheld and his election annulled in April 1869.
