According to a report in The Times, the assets were dumped after the tide of business opinion, while never with the Yes camp, has turned with a vengeance.
As a further indicator of the seriousness with which the No campaign is treating the 18 September referendum, George Osborne and Mark Carney have both said they will not attend a G20 meeting in Australia.
In a response to the postulating of the business community, SNP nationalist, Jim Sillars, threatened a "day of reckoning with BP and the banks" if Scotland voted yes.
The results of the referendum have become too close to call, with one opinion poll from the Sunday Times last week putting the Yes camp marginally ahead.
As our analysis shows, the bookies aren't impressed: they believe that there is an 82.6 per cent chance that the UK will stay together.
