The controversial post was made by Dr Eric Feigl-Ding, an epidemiologist and senior fellow at the Federation of American Scientists. Thousands of Scotland fans, many without tickets, descended on London for their June 18 Euro 2020 match versus England.

       Data from Public Health Scotland later linked the London visit to 1,294 coronavirus cases.

       Scotland were only allocated 2,600 seats at Wembley, meaning many fans travelled without tickets.

       Instead, they congregated around Leicester Square and Hyde Park.

       Supporters were pictured singing and dancing in large groups, with social distancing guidelines largely being ignored.

       Taking to Twitter on Friday, Dr Feigl-Ding said: “Bad news for UK and the rest of the world.

       “Hospitalisations in England due to #DeltaVariant are now accelerating upward even faster than before, according to new data compiled by Covid-19 Actuary Response Group.

       “Cases, hospitalizations, and deaths all increasing in the UK.

       “Scotland cases now at all time record high too. Israel cases and hospitalizations up too.

       “England is also responsible for an outbreak in Scotland among soccer fans who travelled to London. Again all #DeltaVariant.”

       Scotland currently has the highest coronavirus infection rate of any UK nation.

       Britain is fighting a surge in Covid-19 cases as a result of the Delta variant, first identified in India.

       Whilst cases have rocketed, deaths have remained relatively low, suggesting the vaccines are working.

       Dr Feigl-Ding was taken to task by some users, who argued it is unfair to blame England for Scottish fans contracting coronavirus.

       One posted: “England responsible?

       “The Scots came here, ignored social distancing, spread it between them and then returned to disperse it... How is that our fault?”

       Another added: “How is England responsible exactly?

       “The Scottish fans came in their droves unmasked on public transport and ignoring social distancing.

       “Why is that England's fault exactly???”

       A third posted: “The Scots, who despite being told to stay home, travelled to England are responsible.”

       A fourth commented: “Er, no, Tartan Army and Scot Exec [Executive] is responsible.”

       Italian authorities have instructed England fans not to travel for Saturday’s match against Ukraine in Rome.

       Police say any supporter who has been in the UK over the past two weeks will be denied entry to the stadium.
