Ministers have yet to decide whether international fans will be allowed to attend the Euro 2020 finals.
The Government announced today that 60,000 fans will be allowed into Wembley for the semi-finals and final of the tournament.
But details on international fans attending the matches - and whether arrivals in the UK from amber list countries will be exempted from quarantine rules - are still being "finalised", the Mirror understands.
The decision to allow a 20,000 increase in capacity for the semi-finals, played in early July, and final on 11 July comes the week after prime minister Boris Johnson pushed back the easing of restrictions on social distancing from 21 June to 19 July.
Those attending the fixtures will need to provide proof they have received two coronavirus vaccines or a recent negative test.
But border rules mean anyone arriving in the country from all-but a handful of countries will have to isolate at home for up to ten days after their arrival in the UK.
If the rules stand, it means anyone hoping to attend from overseas would have to be in the country already.
Uefa has reportedly been pressuring the government to allow tens of thousands of fans into the UK to attend the games - as well as sponsors and VIPs.
Other than the three British teams, every team bar one is from a country on the amber list - with Turkey on the red list.
UEFA tournament organiser Martin Kallen said on Thursday: "We are in discussions for the knockout rounds, especially for the semi-final and final, the obvious question is also to have overseas spectators."
But despite the increase in capacity announced by the government today, it's understood a decision has not been reached on foreign arrivals.
Details are being finalised, with a source saying public health and safety is the "absolute priority".
Culture Secretary Oliver Dowden said: “We are thrilled that more fans will now be able to walk through the Wembley turnstiles and enjoy the finals of EURO 2020.
“As we continue to make progress on our roadmap out of lockdown, keeping the public safe remains our top priority. We have worked extremely closely with UEFA and the FA to ensure rigorous and tight public health measures are in place whilst allowing more fans to see the action live.
“The finals promise to be an unforgettable moment in our national recovery from the pandemic.”
