Despite the criticism he received during the TV debate on independence for Scotland, First Minister Alex Salmond is sticking to his guns and still insisting that Scotland will retain sterling if independence is voted for.
He said a formal currency union with the rest of the UK was the best option, saying: "It's Scotland's pound and we are keeping it."
Leaders of Westminster’s main parties have all said they would not back such an arrangement and have pressed instead for the so-called “Plan B”.
But they have been joined by leading figures in the “Yes” campaign who believe that Scotland should have its own currency.
Mr Salmond set out his position during question time at Holyrood, receiving criticism from Scottish Labour leader Johann Lamont.
"The reason we are keeping the pound in a currency union, and the reason we are so unambiguous about it, is because we are appealing to the greatest authority of all, that is the sovereign will of the people of Scotland," said the first minister.
Labour’s deputy leader has also been pressing for a “straight answer” on currency.
"They want to know what currency they'll get their wages in, what currency they'll get their pensions in, what they'll use to get the weekly shop, how it will affect their mortgages and car loans and what our businesses will trade in," Anas Sarwar said.
Mr Sillars, a former SNP deputy leader, said "Plan B: separate Scottish currency, perfectly normal answer. It happens all over the world, why shouldn't we do it?"
