She said there was much to be done in areas including health and education and that "question marks" still hang over the impact of the Scottish Parliament. She told a fringe meeting at the Labour party conference in Brighton: "We need to ask ourselves some questions about (devolution). Has it made health better in Easterhouse? Has it made education better in Easterhouse? And there are a lot of questions marks over that."
Ms Curran was also asked about potential changes to the Barnett formula, the calculation which governs how much money Scotland is allocated by the Treasury.
Opponents criticise it saying it gives Scots more public spending per head than the English, although areas where the figures are highest are Northern Ireland and London. Two years ago Lord Barnett, who invented the formula, told MPs it was based on population and should be replaced with a new needs-based system.
Ms Curran said: "On (the) very challenging point on what happens to the Barnett formula let me say - and I think there is a challenge to the nationalists here - I do believe that we should allocate public funding on the basis of need and it should not be around just a regional or a national demarcation. And I think that is a challenge to the nationalists in the referendum."
Aides to Ms Curran said she considered the formula already took into account need, adding she was not advocating change to the current system. They also said she did not think the Scotland received too much public spending in comparison to England. "There is no discussion within Labour about reassessing the Barnett formula", a party source added.
