The calls come after seven of the party's borough councillors switched allegiances to the Conservative Party in Great Yarmouth.

The move gives the ruling Tories overall control of the council – the first time for any party in five years.

After announcing their resignations the night before, it was all smiles as the new Conservative councillors posed for photos outside the town hall yesterday with their new colleagues.

He said he thinks the councillors should resign their seats so there is a by-election in their wards, adding: 'Any honourable person would resign.'

Mr Agnew, who is the party's agriculture spokesman called the ex-Ukip councillors 'disgraceful, disgusting and disloyal' and said the Conservatives were not going to be able to deliver on Brexit.

He added: 'If there's no Ukip for people to vote for we're going to end up with the referendum not getting honoured.'

The leader of the Labour group on the council, Trevor Wainwright, said the defections were pure opportunism.

Great Yarmouth was once a shining light for Ukip.

In March a senior figure in the party, Patrick O'Flynn, even called Yarmouth 'a jewel in the crown' for Ukip on a visit to the town.

Their insurgency started in May 2014 when local elections were held at the same time as the European Parliamentary elections and the party won 10 of the 13 seats up for grabs in the borough.

In May 2016 the party picked up a further four seats which, following two councillors becoming independents, took their total to 12 and made them the second biggest party.

A spokesman in the office of Ukip leader Henry Bolton said he did not wish to comment on the defections at this time.

Not all good news for the Tories

While the Conservatives have gained control of the council in Great Yarmouth, in neighbouring North Norfolk the party has lost control.

Following a string of resignations over the past months, eight Tories have now chosen to sit as independents, which means no party is now in overall control of the district council.
