Foreign Secretary Dominic Raab says the UK and EU are entering the "moment of reckoning" over a post-Brexit trade deal - and spoke of the two remaining sticking points ahead of crunch negotiations this week.
Britain's chief Brexit negotiator, David Frost, will meet the EU's chief negotiator, Michel Barnier, in London next week.
Asked about the talks on Sophy Ridge On Sunday, Mr Raab said: "This week is the moment of reckoning."
He said there were only two "bones of contention" left - fishing and state aid - and that the UK was only asking to be treated like any other country.
"I don't think that sounds unreasonable, I think it's plain common sense," he said, accusing Brussels of "double standards".
Mr Raab said an agreement was "there for the taking" despite reports Downing Street thought there was only a 30-40% chance of a deal.
Mr Frost has said Europe should "take our position seriously". The UK "will not blink first" when the eighth round of talks begins on Tuesday, he told The Mail On Sunday.
And he contrasted Boris Johnson's gung-ho attitude with that of his predecessor Theresa May.
Lord Frost told the newspaper: "We came in after a government and negotiating team that had blinked and had its bluff called at critical moments, and the EU had learned not to take us seriously.
"So a lot of what we are trying to do this year is to get them to realise that we mean what we say and they should take our position seriously."
Mr Barnier will touch down in the UK just hours after Lord Frost takes up a seat handed to him by Mr Johnson.
His arrival comes as the two sides remain unable to agree on big issues such as fishing rights and government subsidies for business.
