Scientists voice concern that supporters who have tickets for the Euros, Wimbledon and Silverstone may not be aware of risks
People attending major sporting events over the next few weeks should be told explicitly that they are taking part in potentially risky research, scientists have warned.
Approximately 40,000 fans are due to attend England’s clash with Germany at Wembley on Tuesday, while the crowd will be 60,000 for the semi-finals and final next week. Tens of thousands will head to Wimbledon from tomorrow, while next month 140,000 are expected at Silverstone for the British Grand Prix.
