A row has erupted in Reform UK after Nigel Farage unveiled his new top team.
The Reform leader announced that Boston and Skegness MP Richard Tice would be taking over from former MEP Ben Habib as his deputy.
Ashfield MP Lee Anderson will become chief whip, while entrepreneur Zia Yusuf will replace Mr Tice as chairman.
Clacton MP Mr Farage said: “These appointments are the first step to ensure that Reform UK is fit and ready to take forward its positive message.
“I have no doubt that we will professionalise the party and change politics for good.”
But Mr Habib said he was weighing up his position within the party “more generally” following his ousting.
He said: “I have just been informed by Nigel Farage that Richard Tice is taking over as deputy leader of the party. Consequently I no longer hold that position.
“I am considering my position more generally in light of this change.
“I have long held concerns about the control of the party and the decision-making processes. I will reflect on all of this.
“The key for me is that Reform UK stays true to the promises made to the British people. The movement we have created does not belong to us, it belongs to the people. We are obliged and indebted to the British people.”
Mr Yusuf, who became Reform's biggest donor last month, said it was “an honour” to be appointed as the party's chairman.
He said: “Against all odds, under Nigel Farage's leadership, our people's movement won four million votes, elected five MPs with 98 second places.
“This is just the beginning. The important work of professionalising the party, building national infrastructure and continuing to grow membership has already begun.
“I will bring all my expertise, energy and passion to the role to ensure we achieve our mission of returning Great Britain to greatness.”
