The control of Brecon was disputed between two local Whig families, Morgan of Tredegar and Jeffreys of the Priory. In 1715 the sitting Member, supported by the Tredegar interest, was returned unopposed. In 1722 William Morgan of Tredegar was returned without a contest, but made his election for Monmouthshire, putting up his younger brother, Thomas, who was returned both on this occasion and in 1727 against Priory candidates. On both occasions petitions were presented against his return on the ground that the Priory candidates had a majority of legal voters, but that the returning officer had refused to poll many of them and had also accepted unqualified, i.e. non-resident, voters for Morgan, 60 in 1723 and 39 in 1727.
