RBS confirmed yesterday that it was "investigating options into disposing of Angel Trains" but declined to confirm whether it was in active discussions with potential buyers. It is understood that the bank hired Lazard in order to flush out interest from the private-equity sector , although Barclays and Babcock & Brown , an Australian investment company , are also expected to run the rule over the business. Potential bidders are expected to pay close attention to any tax liabilities attached to acquiring a leasing company (link below.)

Interesting that Andrew Haines has become embroiled in this one....
