The referendum on Scottish independence will be decided by a single in-out question and 16 and 17-year-olds will be allowed to take part under a deal reached by Westminster and Holyrood, writes Malcolm Burns.
Scotland's First Minister Alex Salmond and British Prime Minister David Cameron will meet in Edinburgh tomorrow to sign the deal on running the plebiscite following weeks of wrangling between Deputy First Minister Nicola Sturgeon and Scottish Secretary Michael Moore.
Mr Moore said: "This will be the green light for the most important decision people in Scotland will ever have to make."
Ms Sturgeon said the result would be fully respected by both governments.
The memorandum of understanding between the SNP and coalition governments includes a single question to be answered Yes or No, with no second option on enhanced devolution as had been mooted.
And the voting age will be lowered, in what could be a precursor to a permanent extension of voting rights to younger people in Scotland.
