Scottish Liberal Democrat leader Willie Rennie has proposed "home rule for Scotland in a federal UK" and more financial powers for the Holyrood Parliament.
Speaking at the Lib Dem Scottish conference in Dunfermline at the weekend, Mr Rennie (pictured) endorsed the plan for "major transfers of power and authority" to the Scottish Parliament set out in the Home and Community Rule report, which is led by Sir Menzies Campbell.
Mr Rennie called for: "Constitutional power which gives the Scottish Parliament permanent powers - not powers on loan from Westminster.
"And financial power to the Scottish Parliament, with up to two-thirds of spending raised through taxes controlled in Holyrood."
Challenging the SNP assertion that Scotland could "continue in the European Union on the same terms as now," Mr Rennie also called on First Minister Alex Salmond to "show us the legal evidence and show us that it has been agreed across Europe."
Foreign Minister Alistair Burt's admission that the Cameron government has "supported" a survey of attitudes to US drone strikes in Pakistan's tribal areas amounts to a tacit admission of British involvement.
