(Adds information about Corsair's interest)
May 7 (Reuters) - Private equity firms, including Corsair Capital, were approached to take part in a 400 million pound ($678.62 million)rescue fundraising for the struggling Co-op Bank, according to Sky News and a source familiar with the matter.
However, the source said no serious discussions have occurred between Co-op Bank and Corsair about the private equity firm buying a stake in it.
Co-op Bank nearly collapsed last year after the discovery of a 1.5 billion pound hole in its balance sheet and had to be rescued by bondholders, a move that drastically reduced the stake of its former owner, Co-operative Group.
Sky News, which earlier reported the talks with Corsair, also said that Apollo Global Management had expressed an interest in Co-op Bank.
"In the next few business days we will make an announcement on the capital raise. Until then we are not making any formal announcements," a spokesman for Co-op Bank told Reuters.
The report came on the same day as a review of the Co-op Group by former director Paul Myners was published. The review said the organization should restructure its current 'manifestly dysfunctional' board and make it smaller with more members with business experience.
