Annunziata Rees-Mogg said she was awaiting further details before deciding whether to support Boris Johnson’s new Brexit proposals.
The Brexit Party MEP told talkRADIO’s Julia Hartley-Brewer there was a lot of information “that we just don’t know yet”.
“The details are sparse, it refers to changing the wording of the political declaration to reflect the new ambitions but we don’t know what these changes are,” she said.
“There’s a lot still to come out about this and I think we’ve got to give it a chance to be analysed properly and see what it actually would mean in practice.”
Her response to Mr Johnson’s plans was more restrained than party leader Nigel Farage, who said it was “like putting your head in a crocodile’s mouth and hoping for the best”.
“Boris only wants to change one part of the Withdrawal Agreement. Despite his words there is no guarantee that we will leave the customs union, and any future trade deal needs good faith from the EU side,” he wrote.
Ms Rees-Mogg said she wanted to give the government a chance to prove the deal was “actually Brexit”.
“We’ve got to find out what really is the intention, but what it also will mean in practical terms for the British people, and make sure this deal really works for our democracy,” she said.
And Conservative MP Nigel Evans told talkRADIO he was encouraged by European leaders who said they were prepared to consider the proposals.
“This is the only deal that is available and I think that the European Union would be absolutely bonkers if they didn’t look at this incredibly seriously and now come to the table and properly negotiate it,” he said.
