The UK government has been urged to abandon its "foolish conditions" for a referendum on independence for Scotland.
The Scottish National Party's (SNP) Westminster leader Angus Robertson demanded that the Scottish Parliament be given powers to ballot Scots on their future, without provisos from British government ministers.
Speaking at Scotland questions on 12 January 2011, Mr Robertson said independence would boost Scotland's economy.
"Will the UK government drop its foolish conditions so we can secure that change in the autumn of 2014?" he asked.
His SNP colleague Pete Wishart agreed, urging Scottish Secretary Michael Moore to devolve any legal powers necessary for a referendum "without condition".
Mr Moore repeated his claim that Holyrood lacks legal powers to hold a referendum, but stressed he was "committed" to providing such authority.
He said a referendum would be "made in Scotland for the people of Scotland".
"That's why we have brought forward proposals to make it legal, to make it fair and make it decisive," he told MPs.
Shadow Scottish secretary Margaret Curran said debate over the past week meant a referendum campaign was "effectively under way".
"We need to get onto the substance of the issue," she added.
