evidence: The government has said bus and train companies must decide whether passengers have to wear face coverings on their services from Monday, when Covid rules are relaxed in England. [...] Wales and Scotland both still require anyone travelling on public transport to wear a mask by law, meaning that those taking services that cross the border from England will have notices reminding them to wear a face covering unless exempt. It is the second time this has happened during the course of the pandemic. [...] Rules regarding face coverings are due to be considered next month in Northern Ireland, which is due to ease some Covid measures on 26 July.
