Downing Street sources have told ITV News that the hedge fund manager, Davide Serra, had a "routine" meeting with an official this morning in Number 10.
I understand that Serra had not been specifically asked to discuss any potential deals between RBS and Canadian banks.
Nevertheless, there is intense speculation around what might happen to RBS and when any parts of the bank might be sold.
With the taxpayer being the biggest shareholder in the company, it matters to us all.
The document snapped outside Downing Street on RBS mentions TD/RBC/BMO - in other words, Toronto Dominion, Royal Bank of Canada and Bank of Montreal and say that profitability at RBS is a fraction of those Canadian Banks.
Davide Serra, the hedge fund manager whose documents on RBS were on display in Downing Street, tells me he has, "no comment" on what he was doing there.
In a series of deals in 2008 and 2009 the UK government bought a 81% stake in RBS to rescue the bank.
As shares have struggled to regain their former value there are ongoing concern about how long the bank will stay in taxpayer hands and fears the government could lose money on the deal.
The future of the bank has been much debated, earlier this week there was talk of shares in the bank being given out to taxpayers to get it back in private hands.
Last week saw rumours of plans to split the bank as the Banking Commission met to decide on its recommendations.
Today has seen a hedge fund boss pictured outside Downing Street with papers hinting at Canadian interest in the bank.
Hedge fund boss, Davide Serra, has been snapped going into Downing Street with papers on display which appear to show discussions about RBS and Canadian banks.
With intense speculation over the future of RBS, papers including phrases about making the bank 'more Canadian' are sure to be interesting.
