The number of visitors for a session is licensed by the local authority in advance. We have no ability to monitor, in real time, how many visitors enter a given session.
Therefore the safest way to comply with Test and Trace requirements is to limit the number of visitors for each session by selling tickets up to that limit in advance of the Show.
What that means is that we cannot allow additional visitors into a session without contravening the basis on which the Show has been authorised. The current limit allows us to admit 950 visitors per session and there is no indication that will change.
