* Bobby Douglas stood as an Independent in 2012, nominated as UKIP for by-election and then disowned by the party but remains UKIP on ballot paper
** Ron Davies elected as Independent in 2008 but failed to be elected as Plaid Cymru in 2012 and 2015
Swing Labour to Plaid Cymru ~6 % / 7% since 2012 otherwise not meaningful
Council now 50 Labour, 20 Plaid Cymru, 3 Independent
