The UEFA Champions League Final between Chelsea and Manchester City is set take place under extraordinary circumstances.
British fans travelling to Portugal will be placed under heightened supervision and monitoring to minimise the chances of COVID-19 transmission.
In the biggest mass departure from the UK since the pandemic started, 12,000 ticketholders and others are in Porto ready for the biggest club match in world football.
The match was originally slated to be in Istanbul but was moved to Portugal because it is on the UK government’s travel green list.
There are concerns about an outbreak as infections from the Indian COVID-19 variant are surging in Britain and many fans are in Porto but the mayor is not concerned about an outbreak.
