A government spokesperson told the BBC it was “furious at the level of illegal migrants and asylum hotels”.
“We are working closely with local authorities, property partners and across-government so that we can accelerate delivery,” said the spokesperson.
It added that NHS treatment was prioritised by clinical need, not asylum status.
“NHS organisations are encouraged to engage with vulnerable groups of people who would otherwise fail to seek help when they need it, and in some cases, this may include asylum seekers,” it said.
“This early intervention work is important in ensuring people access any necessary treatment when they need it in the most appropriate setting, rather than presenting with a more serious condition at a later stage and placing further burden on urgent care services such as A&E.”
