Businessman Sir James Dyson has said it is time to walk away from the Brexit negotiations.
The entrepreneur, who campaigned for Leave in the referendum, said it was quite outrageous that Brussels was demanding "billions and billions".
Sir James also called for an end to corporation tax, insisting there were better ways to impose levies on companies.
He told BBC One's The Andrew Marr Show: "Demanding billions and billions to leave is quite outrageous and demanding it before we negotiate anything is outrageous.
"So, I would walk away. I think that's the only way to deal with them."
Sir James said he believed 90% of future growth would come from outside the EU.
