One of Labour's attack ads.Patients would be forced to pay for NHS treatment if Nigel Farage became prime minister, Labour has claimed.The party will use previous comments the Reform UK leader has made about the NHS in a new ad campaign ahead of the local elections in May.In 2012, Farage said: “I think we’re going to have to think about health care very, very differently. And I think we are going to have to move to an insurance-based system of health care.”And in January this year, he told LBC that he was “open to anything” when asked if he was open to an insurance-based funding model for the NHS.According to Labour, evidence from other countries suggests such a system could see patients charged £120 for a GP appointment, £1,300 for an A&E visit and as much as £23,000 for a hip replacement operation.The party plans to hammer home that message during an “NHS day of action” they have organised for Saturday.The move is a sign of the threat Labour bosses fear Reform poses at the English local elections on May 1.Recent opinion polls show Farage’s party running neck
