As a follow up I've read this today:
Ministers refuse to share asylum hotel locations with delivery firms
"The Home Office is refusing to share information requested by food delivery companies who want to prevent small boat migrants working illegally in the gig economy.
Deliveroo asked Dame Angela Eagle, the minister for border security and asylum, and Home Office officials to provide the locations where asylum seekers are being housed in hotels.
It said that it needed this data to enable them to identify and block their courier’s accounts being used from these locations."
I think that if you are already working illegally, you are more likely to use an illegal means of transport to help with that. Its hard to criticise the delivery companies if they are being denied the means to identify the illegal workers.
