Mark Reckless, UKIP AM for South Wales East and a former UKIP MP, added: "Nigel Farage's greatest achievement will always be getting a referendum to leave the European Union and restore our independence".
Nigel Farage is the latest United Kingdom politician to jump the Brexit ship, announcing his shock resignation in a press conference on Monday.
"The victory for the 'Leave" side in the referendum means that my political ambition has been achieved.
"I was persuaded to come back for one reason and that was to fight this referendum", Farage, 52, said.
Farage says that whoever is chosen to lead the country should be a "Brexit prime minister" and says that he will continue to support UKIP. Her position differs from favorite Theresa May, who backed the "Remain" campaign and believes Article 50, which starts the formal process of European Union withdrawal, might not be invoked until next year.
He said he now wants a cross party team to negotiate the UK's exit from Brussels but he said the most important thing was that the team knows how to win the best deal.

In his resignation speech, he told the audience "I want my life back" and Church responded, "I want my f**king European Union back you piece of s**t!!!!!!"
Also, he said will retain his seat in the European Parliament to see out the negotiations for Britain's exit from the EU following the country's June 23 referendum. This time, he said, there's no chance he'll turn back. I have never been and I have never wanted to be a career politician.
Mr Farage has previously quit the party's leadership in 2009, before becoming re-elected to the position a year later. However, he soon changed his mind and returned to the job.
"I think that UKIP is going to, during this period, maintain it's strength in the country. I'm not, let's just be clear, I'm not walking out of here in a fit of pique, I'm saying I'm fully behind the party, what it stands for, whoever the new leader is", he said.
The short-term tactic worked, and the Conservatives were returned with an overall majority at the 2015 General Election, while Farage himself was not elected.
Farage and the UKIP have taken a hard line against immigration and the EU's emphasis on freedom of movement, calling for stricter measures at the border.
