ALLOWING 16-year-olds to vote in the referendum is nonsensical and sets "a dangerous precedent", MPs have been told.

In a statement at Westminster on the inter-governmental deal on the running of the poll, Conservative backbencher Anglo-Scots MP Sir Gerald Howarth said the age group were precluded by law from many activities – but would be allowed a say in one of the greatest constitutional issues of our time.

He said: "I do believe the proposal to extend the franchise to 16-year-olds, who cannot lawfully buy alcohol, they cannot drive a motor car or be called to fight on the frontline and are now being invited to decide one of the greatest constitutional issues of our time, is surely a nonsense and a dangerous nonsense in so far as it would create a dangerous precedent."

Scotland Office Minister David Mundell said the franchise for parliamentary and local government elections across the UK would still be determined by Westminster. He stressed the UK Government had no proposals to change the voting age nor was there a Commons majority to do so.

Mr Mundell urged his colleagues to take their arguments to Scotland so the SNP Government could be held to account in wanting to extend the franchise.

Labour's Jack Straw, the former Home Secretary, pointed out that when the Electoral Commission last considered whether 16 and 17-year-olds should vote, it found 78% of the British public, including Scots, were against such a change.

He said: "Whatever opinion this House and members of the public may take on the issue, why doesn't the minister acknowledge that the question of the franchise for referendums as well as elections is plainly by law a matter reserved to the UK Parliament and not to any devolved administration?"
