Invesco Perpetual is offering investors the opportunity to back the re-birth of Northern Rock, one of the earliest victims of the financial crisis, through Invesco’s wholly owned subsidiary WL Ross & Co private equity funds.

According to investors, the US asset manager is looking to bring £500m into the funds, run by US billionaire and turnaround specialist Wilbur Ross, which bought investments in Northern Rock and the Bank of Ireland at discounts of about 40%.
