A South Yorkshire MP has written to business secretary Vince Cable calling for more action to be taken on equal pay.
Rotherham MP Sarah Champion is campaigning for large companies to publish details of the differences in what they pay to male and female staff.
She said: “I’ve written to the business secretary calling on him to support equal pay and get on with implementing pay transparency.
“I was delighted when my motion received such huge support from fellow MPs last month yet find myself incredibly frustrated that the Government is still to act on it.
“Women across Britain are still earning on average 81p for every pound a man earns and in Rotherham that drops to 77p for every pound.”
