Valentia, whose bisexual and dissolute father had succeeded as 2nd earl of Mountnorris in 1816, unsuccessfully contested county Wexford in 1818, when Mountnorris blamed his defeat on lack of support from a coalition partner Lord Stopford*. At the 1820 general election he offered again, according to the Catholic press as a supporter of emancipation.
At the 1830 general election Valentia offered again for county Wexford, where the sitting Members had retired, promising to oppose taxation and the monopoly of the East India Company and ‘not be an absentee’. With strong support from the Protestant clergy he was returned in second place.
At the ensuing general election Valentia offered again, explaining that he had voted against the Wellington ministry ‘for not acceding to the call of the country in their demand for retrenchment’ and protesting that the ‘visionary’ reform bill would not ‘serve the country, clothe or feed the poor’ and ‘would disappoint the expectations of the people’. He promised to ‘vote for a more moderate reform’ and according to Stopford, now his ‘staunch supporter’, to support ‘any change in our representation that may intend to improve it’.
Annesley died v.p. and intestate in March 1841 whilst in Brighton.
