Boris Johnson has said he believes there is “a deal to be done” on post-Brexit trade with the EU.
But while the UK prime minister “very much hopes” to come to an agreement, he said the country was “very well prepared” to move on without one.
Mr Johnson made the comments ahead of a call with EU Commission President Ursula von der Leyen on Saturday.
The National Audit Office has warned of “
significant disruption” when the Brexit transition period ends.
The UK left the EU on 31 January and entered the transition period – continuing to follow many EU rules – while a trade deal was negotiated.
But while both sides said a deal needed to be done in October, they have yet to come to an agreement, and talks between the negotiating teams have intensified.
The transition period is due to come to an end on 31 December, meaning the UK would trade with the EU on World Trade Organisation rules – meaning tariffs are imposed – if a deal is not in place.
Critics say this could cause damage to the UK economy, but the government insists the country will prosper with or without a deal.
Earlier this week, both the UK and EU’s chief trade negotiators warned of “wide” and “serious divergences” between the two sides.
Sticking points include fishing rights, competition rules and how a deal would be enforced.
Asked on Friday if the UK could get a deal in the next 10 days, Mr Johnson said: “I very much hope that we will, but obviously that depends on our friends and partners across the Channel.
“I think there is a deal to be done, if they want to do it.
“If not, the country is, of course, very well prepared. As I have said before, we can do very well with on Australian terms [without a deal], if that is what we have to go for.”
Thomas Byrne, Ireland’s minister for European affairs, said the talks up to this point between the EU and UK’s negotiators, Michel Barnier and David Frost, had been “difficult”, with “big issues” still remaining.
He told BBC Radio 4’s Today programme: “I personally don’t expect that there would me major progress today, but at the same time I think it’s very good that they are talking – I think that’s really positive. But I’m not sure that we would expect a moment at this point.”
Mr Byrne was also asked if there could be a “new dynamic” to discussions between the UK and EU if Joe Biden was elected the US president, saying it was “certainly possible”.
Mr Biden, who has Irish roots, said in September that he would not allow peace in Northern Ireland to become a “casualty of Brexit” if he was elected president.
Mr Byrne said: “He was very clear in his suggestion and statement on the 16th of September that any trade deal between the US and UK must be contingent on respect for the Good Friday Agreement and preventing the return of the hard border.”
