Brexit Party MEP Annunziata Rees-Mogg has dismissed claims her party will become defunct once Brexit is delivered.
The politician said the formation of the Brexit Party was about more than just leaving the EU.
"This is about more than just Brexit. It’s about trusting our politicians, it’s about returning faith in the democratic system - that is what has come under so much stress in the last three years," she told talkRADIO's Julia Hartley-Brewer.
"It is really important to remember that democracy needs plurality of views. It needs for electors to be able to choose the type of party that suits them best.
"We are not the Tories with Brexit, we are a much more balanced party."
Her comments came as Prime Minister Boris Johnson refused to rule out holding a general election as early as November 1 - the day after Brexit day - if he were to lose a vote of no-confidence in the Commons.
It led to speculation that the Brexit Party could struggle to win further support if Britain had already left the bloc under Mr Johnson.
But Ms Rees-Mogg disagreed.
"We will be taking on Labour in their heartlands, we will be taking on Tories in theirs. It's to hold them to account and make sure they stay honest," she said.
"Can we trust Boris Johnson? His track record is not great.
"Excuse my scepticism on words being delivered. We heard from Theresa May over a hundred times that we would leave on March 29, it didn't happen."
