A Freedom of Information request from the Ham&High has revealed that the Royal Free spent more than £400,000 on sending 1,700 patients to the Premier Inn in Hampstead in 2016, for cancer, rheumatology, gastroenterology, neurology and respiratory treatments.
This is ten times more than the hospital was spending in 2010.
The bill has steadily gone up by 63 per cent from more than £220,000 in 2012, to £360,000 in 2015, and includes patients travelling from around the country for specialist treatment.
