There is speculation that the deal on the Scottish referendum agreed by the Prime Minister David Cameron and Scotland's First Minister Alex Salmon will include a vote for people ages 16 and 17.

Ben Page, chief executive of IPSOS Mori, told the Today programme's John Humphrys that "turnout is so low on 18 to 24 year-olds so low that just giving votes to 16 and 17 year-olds is unlikely to make a major difference".

Labour MP Natascha Engel supported the move as an opportunity to show that "when you do give the votes to 16 year-olds... the sky doesn't fall in".

Lord Forsyth, the former Scottish secretary, went on to criticise Alex Salmond, accusing him of "attempting to bully" the prime minister to agree to 16 year-olds voting in Scottish referendum.
