Health Measures at UK Borders

My hon. and learned Friend the Member for Edinburgh South West (Joanna Cherry) wrote to the Home Secretary last April raising concerns about passengers entering the UK via airports without health checks or quarantining. Five weeks later, the Home Secretary replied to her stating that, in her view, 8 June was the right time to introduce a requirement on passengers to self-isolate for 14 days, that they could be contacted to ensure compliance, and that any breach of compliance was punishable with a £1,000 fine. Can she update the House: how many £1,000 fines were issued as a result of this, and does she regret her role in the Government’s dithering over quarantine while covid accessed our communities through airports?
