The Prime Minister told Bloomberg:
As for when we get it back into the private sector, I just have two very simple concerns: one is we must make sure this bank contributes to the recovery of the UK economy; secondly, people put their money in - I want them to get their money out.
As we work with this bank as it's nursed back to even further health, the public want to know 'Am I going to get my money back?'
I think they are more interested in getting their money back than the time. Let's get it right.
He also paid tribute to the bank's outgoing chief executive Stephen Hester:
He's done an enormous amount to shrink the balance sheet and to get the bank into a more healthy position, to get it out of crisis and into recovery.
ITN's Deputy Political Editor Chris Ship explains why Stephen Hester's time ran out at RBS.
The man in charge of steering RBS back into private hands - retrieving £45bn of taxpayers cash in the process - is to leave the bank.
RBS chief executive Stephen Hester has announced he is to leave the taxpayer owned bank. But was he forced out or did he jump.
