Speculation that Mr Lansley will be forced to resign has been growing since Prime Minister David Cameron stepped in to announce the Bill will be paused while a ‘listening exercise’ was carried out.
Reports over the weekend also suggested that Mr Cameron and Deputy Prime Minister Nick Clegg discussed whether Mr Lansley would retain his role as health secretary once the listening exercise is completed.
But Downing Street said the speculation that Mr Lansley would be forced to resign was ‘nonsense’.
A spokesman said: ‘Andrew Lansley is doing an excellent job.’
Mr Lansley suggested he would quit the cabinet if he is forced into another role. He is reported to have said: ‘I've stopped being a politician. I just want to get the NHS to a place where it will deliver results.
‘I don't want to do any other cabinet job. I'm someone who cares about the NHS who happens to be a politician, not the other way around.’
