With regard to the digital Covid certificate, we will give consideration to the testing option for the exact reasons the Deputy has mentioned. However, in giving that consideration, we also need to be honest with people. Nobody will ever say that any test, whether a PCR test or an antigen test, is as good as vaccination or immunity from exposure. We could do that in order to address the unfairness and inequality issues the Deputy has raised but it would make things less safe. We need to be honest about that.
