Business secretary Vince Cable has written to Scottish legal authorities to push for a fast decision on whether to prosecute former Royal Bank of Scotland directors.
The BBC reports Cable wants a quick resolution to the situation to maintain public confidence.
RBS required a £45.5bn public funded bailout in October 2008.
In December 2011, an FSA report said RBS was ruined by “multiple poor decisions” and a £50bn “gamble” on buying Dutch bank ABN Amro.
In January 2012, RBS chief executive Fred Goodwin was stripped of the knighthood he was awarded for services to banking.
The Crown Office of Scotland announced last July it was launching a criminal inquiry into the Scottish banking sector including the failures of RBS and its directors.
A letter from Cable to Scottish law officer Lord Wallace has asked for a progress update but Cable insists he is “not seeking to influence the outcome” of the legal process.
The letter said: “Given that this matter was referred to them in January 2012, I am very keen for a decision to be reached as quickly as possible in order to maintain public confidence in the efficiency of the decision-making process.”
Cable added public and media interest in the banking sector and RBS remains high.
