The UK government needs to level the tax playing field to encourage more businesses to become employee owned, according to the great grandson of John Lewis.

Patrick Lewis, the only member of the original founding family working at the retail giant, also warned that it is too complex to set up an employee owned company at the moment.

"The first element, for any business setting up, is making sure that the tax playing field is level," the director of partnership services at the John Lewis Partnership said.
