Scientists advising the government say they are frustrated at the delay in making the research public
Scientists advising the government on research into pilot mass events such as concerts and sports matches are frustrated at the delay in making the findings public and have been pressing for them to be released, the Guardian has learned.
Some of the events, which have included the Download music festival, the snooker world championships and a club night in Liverpool, took place as long ago as April and government sources say the results have been encouraging.
