Ed Miliband has said his "radical" proposal to link the minimum wage to the national average is the biggest change to the system since it was introduced 15 years ago.
The Labour leader said there is a "low pay epidemic" in the country with over five million people on low pay in Britain.
Mr Miliband unveiled his plans during a speech in Walsall, with a member of his staff recording his speech on Twitter:
Today, I am proud to announce that the next Labour government will take new radical action against low pay. -Ed
We will set a target for the next Parliament designed to move the National Minimum Wage closer to average earnings by 2020. -Ed
There is no future for Britain competing on the basis of low pay with the sweat-shops of the world. -Ed
