SCOTTISH school pupils should be educated about the independence referendum now the vote has been extended to 16 and 17-year-olds, according to a leading parents' group.

The Scottish Parent Teacher Council (SPTC) said the referendum was a significant opportunity to engage young people and their families in the wider political debate.

Teaching unions have already called for resources and guidance to be made available to schools and colleges on a non-partisan and non-party political basis to help inform young people about the decision in 2014. However, former Scottish secretary Lord Forsyth of Drumlean said the issue had huge implications because it would "bring politics into our schools".

A statement from the SPTC said: "We believe the forthcoming referendum is a legitimate and indeed valuable learning opportunity with which our schools should engage in a meaningful way."

It has suggested a number of events to engage parents, including debates and topics for home discussion.

The statement came as ministers again rejected calls for prisoners to be given the vote in next year's independence referendum.

The LibDems, backed by the Scottish Greens, want prisoners serving four years or less to be allowed to vote.

Apart from the addition of 16 and 17-year-olds, the franchise for the referendum will be the same as for Holyrood and council elections.

MSPs last night backed the Scottish Independence Referendum (Franchise) Bill by 97 to 12, with the Tories opposed.
