Alex Salmond dismissed recent gloomy economic figures for Scotland under the reign of the Scottish National Party (SNP)
However, during an entire interview on the Andrew Marr Show, the former SNP leader failed to spell out how his nationalist party would recover the losses.
Scotland's economy has shrunk in the last quarter, losing thousands of jobs, while in contrast Britain's economy grew during that period.
In an interview this morning with Andrew Marr, Mr Salmond said the SNP could not do anything to stop this economic downturn.
Salmond quizzed over Scottish referendum plans
The former SNP leader insisted that Scotland would regain the job losses, before warning Britain that its post-Brexit boom will falter.
But, Marr continued to point out Scotland's feeble job figures as well as the fact that "at least half of the people in Scotland do not want a referendum".
The SNP International Affairs Spokesman turned from the gloom-and-doom economic news to firm promises of Scottish independence.
He told Marr: "Theresa May’s line will crumble. No British Prime Minister can stand in the way against the democratic wishes."

Mr Salmond added: "Even Thatcher was able to recognise the self-determination of the Scottish people.
"Theresa May's line that now is not the time is not going to stand.
"David Cameron's line did not stand and neither will Theresa May. Her line will crumble.
"Take my word for it, there will be a referendum in Scotland. We will have that choice."
The Scottish MP also remained adamant that "the proportion of people in favour of independence will grow".

He then warned that "self-determination delayed is like justice, self-determination denied".
Later on the Andrew Marr Show, Mr Salmond said: "The right time for an independence referendum is when the British Brexit deal is known so the Scottish people can decide between Brexit and an independent Scotland in Europe.
