The U.K. will most likely fail to strike a new trade agreement with the European Union by the end of the year, analysts said, as the coronavirus crisis threatens to derail official trade talks.
Prime Minister Boris Johnson has pledged to conclude a post-Brexit trade deal this year. The U.K., which left the bloc on Jan. 31, is in a transition phase until December. During the transition, it is working to establish trade arrangements with the 27-nation EU.
However, this timeline is now at risk after the two lead negotiators had to isolate due to Covid-19 infections.
"The pandemic has completely taken over the agenda in both the EU and in London, and relegated the Brexit talks to a secondary issue," Constantine Fraser, European political analyst at research firm TS Lombard, told CNBC on Thursday.
"It was always going to be difficult to reach an agreement in the limited time available this year. The pandemic means it will now be impossible."
British and European negotiating teams held a call on Wednesday for the first time since both lead negotiators were forced to self-isolate.
The EU's negotiator, Michel Barnier, tested positive for the virus in March but he has now recovered. The U.K.'s Johnson announced he had also tested positive for the virus last month. He was discharged from hospital on April 12 after three nights in intensive care, and continues to recover.
U.K. negotiator David Frost said Downing Street had no intention to ask for an extension to the current transition period. A U.K. government spokesman repeated Thursday that London will not ask for a delay.
"The government insists that all is on track, but we all suspect not," Vicky Pryce, chief economic adviser at the Centre for Economics and Business Research in London, told CNBC on Thursday.
"I am hearing that quite a lot of civil servants who were doing Brexit have been moved temporarily to coronavirus and that must delay the putting into U.K. law what was EU law," she continued.
Legally speaking, the U.K. has until July 1 to extend the ongoing transition period. The delay could last up to two years, meaning December 2022.
A spokesperson for the European Commission, the EU institution which negotiates with the U.K. on behalf of the 27 remaining EU countries, told CNBC it stands ready to discuss an extension
It is up to the U.K. government to start this discussion.
"We should not rule an extension out despite the official position. (U.K.) ministers would likely accept a six- or 12-month delay given the circumstances," Kallum Pickering, U.K. economist at Berenberg, told CNBC on Thursday.
Anna Rosenberg, head of Europe and U.K. at the political risk advisory Signum Global, said the coronavirus crisis had increased the odds of an extension to 60% from 20%.
"The U.K. will however find a way to save face, most likely refusing to ask for it outright and/or encouraging the EU to grant that extension in their own right. You could also very likely see a last-minute extension, in December, not in June, presented as a 'phase 2 negotiation' rather than an extension," Rosenberg said.
The U.K.'s Conservative Party won a comfortable parliamentary majority in a general election in December 2019.
