Ukip faced an embarrassing political defeat in the Brecon by-election after their candidate received fewer votes than the Monster Raving Loony Party.
Candidate Lady Lily Pink claimed an 334 votes, beating Ukip’s Liz Phillips, who received only 242 votes.
The Monster Raving Loony Party’s manifesto states they will ’send Noel Edmonds to negotiate Brexit because he understands Deal or no Deal’.
It adds: ‘There will be no need for backstop for the Brexit negotiations. We’ll have Alex Stewart as wicket-keeper.’
Ukip’s disastrous night was a further setback following their damaging defeat in the European elections.
Gerard Batten quit as leader on June 2 after Ukip was wiped out at the European elections by its former leader Nigel Farage’s new Eurosceptic group, the Brexit Party.
Ukip's role as the principal voice of Euroscepticism has been wrested from its grasp by the Brexit party, which took 3,331 votes in the Brecon by-election.
Ms Phillips accused the Brexit Party, of being "only a party in name", claiming that unlike Ukip, it does not offer people full membership.
"Ukip was the party that brought about the referendum and is the one that stayed firm all the way through," she said.
Ukip's leader has lost his seat at the May European Parliament elections, in a blow for the disintegrating party.
Gerard Batten has held his seat in London for a decade but was defeated after many of his voters switched over to the Brexit Party.

Coming in third, Nigel Farage’s Brexit Party beat the Labour Party, which came in fourth with 1,425 votes.
Ukip came last with just 242 votes even losing out to the Monster Raving Loony Party, which got 334.
