In an interview with The Sunday Times, the Brexit secretary said the negotiations would be plunged into "crisis" from the off because the EU refused to discuss a trade deal until Britain agreed to pay up.
In a warning shot at Brussels, Davis said the other member states would have to shift their position if they wanted to see progress, declaring that he regarded even "£1bn as a lot of money".
Earlier, the British Prime Minister Theresa May said that Brussels must pay its own Brexit bill of billions of pounds for Britain's share of the European Investment Bank and other joint projects. She insisted that the UK has financial "rights" that must be respected during discussions about payments as well as "obligations" to the body it is leaving.
