Tory MPs are unhappy with Scots MPs voting on England-only matters

UK Tory leader David Cameron is backing calls for Scots MPs to be prevented from voting on English issues.

But Glasgow South Labour MP Tom Harris' Commons motion said MPs should have the same rights.

Prime Minister Tony Blair said it would be "utterly irresponsible" to limit the voting rights of some MPs.

The West Lothian question was first posed by Tam Dalyell in the 1970s.

It asked why Scottish post-devolution MPs should be allowed to vote on Westminster matters, like health or education, but could not vote on issues that would be devolved to a Scottish Parliament.

'Astounding complacency'

Speaking in the Commons on Tuesday, junior Scotland Office minister David Cairns described the Tory proposal as "daft."

But the shadow Scottish Secretary David Mundell accused ministers of "astounding complacency" in failing to deal with the issue.

It is believed some English Labour MPs share Tory concerns on the voting issue.

Tony Blair said it was "an essential part" of the British constitution that there was only one class of MP.

Referring to the West Lothian question he said it would be "utterly irresponsible" to limit some MPs' voting rights.
