Liberal Democrat leader Nick Clegg has insisted he is 'sceptical' about the idea of paying different salary levels to public sector workers in different parts of the UK.
His comments come ahead of Welsh Lib Dem efforts to persuade the party to halt plans for regional pay.
And they appear to be at odds with earlier support for the plans from fellow Lib Dem minister Danny Alexander.Mr Clegg told political editor Adrian masters:
No decision has been taken. We will not take any decision unless there is overwhelming evidence that it helps everybody and if there isn't, I've set the bar very high, of course we won't do this.
