evidence: On 10 August 2020, the use of face coverings in indoor settings such as shops and shopping centres in Northern Ireland became mandatory. On 1 October 2020, the PSNI’s Chief Constable Simon Byrne and Assistant Chief Constable Alan Todd, at a meeting of the Northern Ireland Policing Board, suggested that there was 90% compliance with the regulations on wearing face coverings in retail settings. [...] The figure of 90% compliance with the wearing of face coverings in retail settings in Northern Ireland cannot be substantiated. It is an estimate from the PSNI based on a variety of informal/anecdotal feedback.
