David Davis has firmly stated the UK will not pay £50 billion to the EU in a so-called 'divorce bill.'
European Commission president Jean-Claude Juncker last week told the BBC the fee would be around this amount to cover the country's liabilities.
It now appears this fee will become one of the obstacles in the negotiations, to be begin officially once Prime Minister Theresa May triggers Article 50 on Wednesday.
In an appearance on BBC Question Time, the Brexit Secretary said the UK would meet its obligations, but he made clear the reported sum would not change hands.
He said: "Ms May said we're coming to the end of when we are paying enormous sums to the EU.
"Of course we'll meet our international obligations but we expect our rights to be respected as well.
"I don't think that sort of money will change hands."
