MPs are debating proposals which could see NHS staff paid different rates for the same job in different parts of the country.
Labour's Shadow Health Secretary told MPs that a cartel of twenty trusts in the South West are collectively trying to force changes to the terms and conditions of 88,000 local staff.
Mr Burnham also claimed that there were worrying signs of trusts in the North East coming together to push through similar changes.
The Health Secretary Jeremy Hunt said the government has no plans to introduce regional pay and was merely implementing a degree of flexibility in local pay bargaining which the last Labour government had legislated for.
