German football fans have been warned not to attempt to travel to Wembley for Tuesday's Euro 2020 last 16 tie against England.
A senior official of the World Medical Association made the warning because of the highly infectious Delta variant of Covid-19.
'Even a vaccinated person who follows the social distancing rules and makes a pilgrimage to the stadium is taking a limited risk,' chairman Frank Ulrich Montgomery said.

'I consider this to be populism and I can only advise against travel to see the games,' added Montgomery.
'I don't understand why Prime Minister Boris Johnson is allowing this.'
