Lloyd began his political career in Swansea where he worked as a GP. In
1995 he sought election for
Cockett ward, hitherto regarded as a Labour stronghold. He made gains at the election, coming close to beating Labour. At a subsequent by-election, however, he was elected as a councillor. In
1999 he held the seat and topped the poll. He was the Senedd Member for
South Wales West from 1999 until 2011, when Plaid failed to win the second seat on the regional list. He served as Shadow Finance Minister for Plaid Cymru in the National Assembly. In
2012, he unsuccessfully sought to regain his former seat in the
Cockett ward on Swansea Council. He was again unsuccessful at a by-election in 2015. He returned to the Senedd as a Member for
South Wales West following the May 2016 election. He announced his decision to only stand in a constituency at the
2021 Senedd election and not on the list, he stood and finished 3rd with 14.5% in
Swansea West in doing so he qualified for a resettlement grant of £31,622 as he was an unsuccessful candidate, something he was criticised for during the campaign. He also received £41,815.44 when he was defeated in 2011. ==References==
