The First Minister's opponents have sought to heap more pressure on him, insisting his credibility is damaged after it emerged that his Government has not yet taken legal advice on a key issue linked to independence.
Labour claimed Alex Salmond's credibility is "fatally damaged" and demanded he make an emergency statement on the issue.
The Tories said that trust in the SNP administration has been "blown apart".
It comes after Deputy First Minister Nicola Sturgeon revealed that the Scottish Government only commissioned "specific legal advice" from its law officers on an independent Scotland's membership of the European Union.
Opposition politicians turned on Mr Salmond, saying that during a television interview he appeared to say that he did take legal advice.
