Even though he suffered from ill-health, most notably a paralysis that restricted the use of his legs, Powell was elected MP for
Cardiganshire, his father's former constituency, at the
1859 General Election, when he defeated Saunders Davies of
Pentre by a small margin. His opponent's father,
D.A. Saunders Davies, had previously served as MP for
Carmarthenshire until his death in 1857. Powell was successful despite the fact that his opponent had the support of the majority of the county's landed gentry, most of whom were located in the south of the county. This was demonstrated by the fact that in the Cardigan district, Davies had a substantial majority. However, in Aberystwyth district, the northern part of the county, where Nanteos was located, Powell won by an even more decisive margin Both candidates were said to hold similar political views and Powell sat in Parliament as a Liberal-Conservative, The fact that he was supported by the former Conservative MP for
Cardigan Boroughs,
John Lloyd Davies, demonstrates that Powell was hardly a radical candidate. ==The 1865 General Election==
