Southport Air Show 2021 cancelled for second year in a row Despite much planning, council says keeping people safe must be priority 13:34, 8 APR 2021 Updated The 2021 Southport Air Show has been cancelled due to coronavirus for a second year running. Sefton Council says it has made the difficult decision due to “continued uncertainty over large scale events”. The news comes after the local authority announced the town’s Flower Show – the biggest in the UK – would also not be going ahead. Both cancellations are a huge blow for the town, with each event bringing in thousands of visitors from across the country and generating millions of pounds for the local economy.
