And with a warning that time was running out in the search for an agreement, he summoned the Tory Cabinet minister’s negotiating team for urgent talks on Monday.
But a source close to the EU Exit Secretary dismissed the summons as a “gimmick” and urged Mr Barnier to “engage” with the proposals Britain had already put forward as a blueprint for a future partnership with the bloc.
Mr Davis’s curt response reflected a tougher stance being adopted by the Government in the Brexit talks following frustration at the repeated stonewalling by the European Commission’s negotiators.
The clash erupted last night as a EU summit in Brussels concluded by noting that “important aspects still need to be agreed” in the Brexit talks.
At the summit yesterday, Mr Barnier claimed the negotiations were being held up by the wait for a promised “white paper” policy document on the UK Government’s Brexit goals due to be published on July 9.
We have made progress but huge and serious divergence remains, in particular on Ireland and Northern Ireland
He said: “We have made progress but huge and serious divergence remains, in particular on Ireland and Northern Ireland.
“Now we are waiting for the UK White Paper and I hope it will contain workable and realistic proposals.
“The time is very short. We want a deal and are working for a deal, the time is short and I am ready to invite the UK delegation to come back to Brussels next Monday.”
The source at the Department for Exiting the EU last night pointed out that no official invitation to go to Brussels had been received.
“This is a gimmick designed for the benefit of TV cameras rather than the negotiations,” the source said.

“A better approach would be to engage with our proposed solutions, and deliver on their commitment to acceleratediscussions about the future – we’re publishing a White Paper and look forward to discussing it.”
EU Council President Donald Tusk also warned that time was running short in the Brexit negotiations, saying: “This is the last call to lay the cards on the table.”
Speaking at a news conference at the end of the summit, he added: “On Brexit, the EU 27 has taken note of what has been achieved so far. However there’s a great deal of work ahead and the most difficult tasks are still unresolved. If we want to reach a deal in October we need quick progress.”
The leaders of the 27 nations staying in the EU after Britain leaves next year yesterday held a brief.
In their summit conclusions, the 27 leaders welcomed the progress on the legal text of the withdrawal agreement but noted several issues still needed to be resolved including the future territorial status of Gibraltar.

The leaders also expressed concern that “no substantial progress has yet been achieved on agreeing a backstop solution for Ireland/Northern Ireland”.
They also demanded “further clarity as well as realistic and workable proposals from the UK as regards its position on the future relationship”.
And in a demand for further concessions from the Government, the leaders said that “if the UK positions were to evolve” the EU “will be prepared to reconsider its offer”.
A statement said: “The European Council expresses its concern that no substantial progress has yet been achieved on agreeing a backstop solution for Ireland/Northern Ireland.
“It recalls the commitments undertaken by the UK in this respect in December 2017 and March 2018, and insists on the need for intensified efforts so that the Withdrawal Agreement, including its provisions on transition, can be concluded as soon as possible in order to come into effect on the date of withdrawal.
Theresa May left the summit at 5am
“It recalls that negotiations can only progress as long as all commitments undertaken so far are respected in full.”
The brief summit discussion about Brexit followed a marathon sessions lasting until 4.30am yesterday as the leaders rowed about the EU’s migration crisis.
Theresa May left the summit at 5am as the discussion about Brexit was restricted to leaders of nations remaining in the bloc.
Mrs May is due to convene an “away day” meeting of her full Cabinet at Chequers next Friday to finalise the contents of the white paper.
It emerged yesterday that the meeting at the Prime Minister’s official country retreat will begin at 10.30am and could continue into the early hours of the following morning.

Ministers have been instructed that they will not be allowed to leave the gathering until a blueprint for new customs arrangements between the EU and UK are agreed.
Aides indicated that ministers will not be staying over at the meeting because Chequers does not have enough bedrooms to accomodate them all.
One Downing Street source said: “Pyjamas will not be required – it will be normal business attire.”
The source added: “They need to agree because it needs agreeing.
“If it runs late into the night they’ll have to keep talking because there aren’t enough beds.”
