Arrivals in the UK quarantine

Today the UK 🇬🇧 government made announcement 📢 that from the 8th June, new arrivals into the UK 🇬🇧 for 14 days. So why so little, so late? I've no idea 💡

Surely this should have been done months ago and now most countries are coming out of lockdown 🔒 the UK 🇬🇧 is going to be locked 🔒 inside, citizens of the UK 🇬🇧 will not leave, knowing that they face severe restrictions on the return entry. Obviously this will completely stop 🛑 other tourists and visitors coming into the UK 🇬🇧 and spending money 💷. This seems more likely to cost millions and push thousands of businesses over the edge into liquidation and bankruptcy
