The UK and EU have said serious differences remain over a post-Brexit trade deal, following the latest negotiations in Brussels.
EU negotiator Michel Barnier said the bloc's position needed to be "better understood and respected" by the UK if an agreement is to be found.
His UK counterpart David Frost said "significant" disagreement remained on "a number of important issues".
The UK has ruled out extending the December deadline to reach a deal.
The latest round of talks, the first to be held in person since the Covid-19 crisis struck, came after both sides agreed to "intensify" negotiations last month.
Negotiations have continued throughout the pandemic via video link. An additional five weeks of in-person talks are planned for July and early August.
BBC Europe reporter Gavin Lee said the latest round of talks had broken up a day early, with a discussion between the two chief negotiators tomorrow cancelled.
