In the 2016 Assembly election Gill won a seat representing the North Wales region. He was beaten to the post of leader of the UKIP group in the National Assembly for Wales by former Conservative MP Neil Hamilton. Farage described the move as an "unjust act of deep ingratitude"  resulting in Hamilton dismissing Farage as simply an "MEP for South East England whose opinions were irrelevant". Gill subsequently left the UKIP group in the assembly to sit as an independent, citing much infighting and distractions. He remained a member of the party and its leader in Wales, until Neil Hamilton was made Wales leader in September 2016. Also in September 2016 Gill's media advisor Alexandra Phillips spoke to The Guardian, stating that she had left UKIP and joined the Conservatives, making comments critical of Hamilton. Staying on as an advisor to Gill, she told BBC Wales that UKIP's foothold in Wales had become "a war zone". Gill resigned as an AM in December 2017.
In March 2016, Reckless was announced as UKIP's lead candidate for the regional seat of South Wales East. He was elected on 5 May 2016.
On 6 April 2017, Reckless left UKIP to join the Conservative Group; however, he did not rejoin the Conservative Party. This move made the Conservative group the second-largest in the Welsh Assembly. Upon leaving, he said, "I leave UKIP positively, having achieved our joint aim, a successful referendum to leave the EU".
On 14 April 2019, Reckless left the Conservative Party Group over the party's failure to deliver Brexit. He then sat as an independent member before joining until the Brexit Party the following month.
On 15 May 2019, Reckless stated his intention to form a new Brexit Party political group, along with Caroline Jones, Mandy Jones, and David Rowlands. He is the current leader of the Brexit Party in the Senedd.
Jones replaced Hamilton as leader of UKIP in the National Assembly on the 17 May 2018 following a vote by the UKIP group.
On 10 August 2018, Jones lost the group leadership finishing last in the 2018 UKIP Wales leadership election in a three-way contest. Gareth Bennett won the contest and replaced her as group leader.
On 12 September 2018, Jones announced that she was leaving the United Kingdom Independence Party citing her reasons as the party moving "to a more far-right position" under Gerard Batten and a leadership election that was "shambolic from beginning to end". She also said that she was a victim of misogyny claiming that she was once told to "shut up" at a meeting. UKIP Group Leader Gareth Bennett admitted that she was told this by a participant, but that "it had nothing to do with her gender". UKIP Wales Leader Neil Hamilton called on Jones to resign her regional list seat and allow another UKIP member to become an AM, which she refused to do.
Party Leader Gerard Batten described her statement as "politically correct twaddle to disguise the fact that Mrs Jones is politically ineffective..
On 15 May 2019, Jones along with 3 other Assembly Members joined the Brexit Party.
When Bennett was selected to contest the South Wales Central electoral region, he was criticised for blaming rubbish problems in Cardiff on students and Eastern European immigrants and was nicknamed the 'Donald Trump of Wales'. This led to senior UKIP figures including leader Nigel Farage and immigration spokesman Steven Woolfe publicly distancing themselves from Bennett. A petition containing the names of 16 other UKIP Assembly candidates opposing Bennett's candidacy was presented to the party's National Executive Committee, which upheld his candidacy. He was elected to National Assembly for Wales as member for South Wales Central in 2016.
In the UKIP Assembly group, Bennett backed Neil Hamilton for leader over Nathan Gill. After Hamilton became leader of the group, Bennett was appointed as UKIP Assembly spokesman for Local Government, Housing and Sport. In April 2017, Bennett was appointed as UKIP's Business Manager in the Assembly. In the same month, the Assembly's Equalities Committee, of which Bennett was a member, published a report about refugees. Bennett brought out his own report, in which he complained that the proposals would encourage more refugees to come to Wales.
In December 2017, Bennett was banned from speaking in the Chamber of the Welsh Assembly for a year by Presiding Officer Elin Jones. The ban came after Bennett claimed that making the process to change legal gender easier would lead society to implode. Bennett refused to apologise or withdraw his remarks, and was barred. In January 2018, Bennett made a partial apology in which he stated that he would accept the authority of the Presiding Officer, and he was allowed to resume his speaking duties without withdrawing his previous remarks.
In February 2018, Bennett led UKIP's opposition to plans to expand the Welsh Assembly's membership.
Bennett claimed almost £10,000 in expenses to set up an office which never opened.
In July 2018, it was announced that there would be a ballot of UKIP party members in Wales to decide the position of UKIP Leader in Wales. The three candidates who announced that they were running for the post were former Assembly Group Leader Neil Hamilton, who had just been ousted from the role; Caroline Jones, who had ousted him; and Gareth Bennett. Bennett's main policy planks included his campaign to abolish the Welsh Assembly, and his opposition to the Welsh Government's Welsh language policies. He won the UKIP Wales leadership election in August 2018, with 269 votes.
On 3 June 2019, Bennett announced that he would be running in the 2019 UK Independence Party leadership election after Gerard Batten stood down as leader. Bennett has claimed that he would take UKIP forward with 'bold policy ideas', after Gerard Batten's one-year term came to an end. Bennett published his 2019 UKIP Leadership Election Manifesto on his website, which includes policies such as 'National ID Cards' ,'UKIP Party Democracy', 'National Volunteer Force', 'Regular Referenda', 'Freedom of Speech', 'Regulating Mosques', 'Scrap Foreign Aid' and 'Abolishing Politicians'. On 11 July, Bennett announced that he would withdraw his leadership bid in order to promote Ben Walker's campaign.
On 7 November 2019, he quit UKIP to become an independent politician
Mostyn Neil Hamilton, MS (born 9 March 1949) is a British politician, non-practising barrister, and former teacher. He has been a UK Independence Party (UKIP) Member of the Senedd for the Mid and West Wales region since 2016. He was previously a Conservative MP for the Tatton constituency from 1983 to 1997.
After being implicated (alongside Tim Smith) in the cash-for-questions affair, Hamilton became widely associated with sleaze; he was defeated in the 1997 general election, and subsequently left politics. He left the Conservative Party in 2002, and joined UKIP. He was elected to the National Executive Committee of UKIP in 2011. Following his election to the National Assembly for Wales, he was UKIP Assembly Group Leader from 2016 to 2018 and again from 2019. He has been Leader of UKIP Wales since 26 September 2016.
- Mandy Jones , Ukip North Wales Replaced Nathan Gill
Jones stood for UKIP in the Clwyd South constituency at the 2015 General Election. She also stood for UKIP in Clwyd South at the 2016 Welsh Assembly election, coming fourth behind Labour, the Conservatives and Plaid Cymru. As the third UKIP candidate on the North Wales regional party list, she failed to secure a National Assembly for Wales seat.
Following the resignation in December 2017 of former UKIP Assembly Member (AM), Nathan Gill, Jones (as the next available UKIP candidate on the regional list) was confirmed on 27 December as the replacement AM. She was due to actively take up her duties following an oath swearing ceremony, which took place on 29 December at the Welsh Assembly's Colwyn Bay buildings.
On 9 January 2018, UKIP Wales announced that she would not be joining the UKIP group in the Assembly, due to employing members of other parties in her office. Jones refused to change her staff and described the UKIP group as "toxic". She describes herself as a Faragist and claims former UKIP leader Nigel Farage supports her actions. Her party membership was suspended on 18 June 2018 following criticism of Neil Hamilton's nomination as an assembly commissioner.
In March 2019, Jones spoke in the Assembly Chamber about the physical and emotional abuse she suffered from her adopted mother, in opposition to the Welsh Government's proposals to ban the smacking of children.
So it seems that Neil Hamilton is now the only Ukip Senedd member and tha's possibly even the rest of bunch of turncoats won't have him.
Whether Bennett and Abolish the Assembly Party slips in to the Senedd next year one wonders how long he would remain. Probably depends on if he's joined with a few others , but I suspect in less than a month they willl be fighting like Kilkenny Cats
