There's been a strong reaction online to the news that former Welsh Office minister Rod Richards has joined UKIP and is said to be seeking selection as one of the party's candidates in next year's European Parliament elections. Plaid Cymru's Dafydd Elis Thomas tweeted his response:
@adrianmasters84 good to see my old political friend wanting to appear in his true colours!
Matthew Evans, who leads the Conservative group on Newport council, said he was sorry to see Mr Richards finally sever links with his party.
But one UKIP tweeter was doubtful about the former minister's chances of winning the support of members of his new party.
