In the first half of 2013, the Co-operative Bank (then a subsidiary of the
Co-operative Group) lost £700m, making the planned expansion of the bank impossible, and raising some warning signs for the bank's customers. Later that year, in May, a £1.5bn "black hole" was found in the bank's accounts. This failing was largely blamed on the bank's chairman,
Paul Flowers and the takeover of Britannica Building Society in 2009. This led to the eventual takeover of the bank by several
hedge funds, to plug the financial gap of the bank, which otherwise would have collapsed. In April 2017, the Co-operative group sold off its remaining 20% stake in the bank, marking an end to
co-operative ownership. At this time, serious questions were raised by the Save our Bank campaign about its ethical status, with the union saying that the bank 'would not stand a chance' if it did not continue with its ethical policy. == History of the union ==
