Four candidates appear to be from from UKIP and its splinters
For Britain is a minor far-right political party in the United Kingdom, founded by the anti-Islam activist Anne Marie Waters after she was defeated in the 2017 UKIP leadership election.Waters left UKIP and formed For Britain after she and her supporters were described as "Nazis and racists" by Henry Bolton and UKIP's former leader The name is taken from her UKIP leadership campaign slogan, "Anne Marie For Britain". Waters said that the party would "speak to the forgotten people". So Hugh Nicklin may wellbe a former Ukip member
The party was founded in 2018 by former UKIP member and Gulf War veteran Gavin Felton and other ex-servicemen of the British Armed Forces. John Rees-Evans, previously a UKIP leadership candidate, was announced as the first party leader, and Gavin Felton named as chairman.
Phillip Taylor may well be a former Ukip member
Neil Hamilton is a current Ukip AM]
Ian McLean SDP may well be the Ian Mclean who stood for UKIP for the Cynon Valey in the 2017 General Election
Richard Suchorzewski, Abolish the Welsh Assembly Party is a former Chair of UKIP Wales,] who defected from the Conservative Party in 2004, and stood for the leadership of UKiP in 2006 where he finished second to Niglel Farage
So plenty of choice for the far right and Leave (I accept they are not the same) in Newport West .
Remain voters seem to have the choice between Plaid, Liberal, Democrats , Greens or Renew, what the veiw of Ruth Jones (Labour) is could be interesting and much may depend whether she supports Corbyn's Lexit position or calls for a People's Vote indeed she may well be in a cleft stick of either backing the Leadership or the majority of her party's MPs .
Much may depend on whether we leave the EU a week before the election with some kind of deal, No deal, an extension of Article 50 and the possibility of a Second Referendum.
