Shadow health minister Diane Abbott has tweeted:

@paulwaugh Agree with charging people who are not entitled to free NHS care. But obvious public health risks re. communicable disease.
Earlier, Labour's shadow health minister Liz Kendall said the government had a "poor record in announcing policies that sound good but prove to be completely unworkable" and they would be asking "many questions" on the proposals.
