A FIRM that has been preparing a class action-style claim against Clydesdale Bank owner CYBG since the middle of 2017 said it will launch its case at the beginning of 2019 after joining forces with a fellow claims management business.

RGL Management, which in July 2017 secured the backing of litigation funder Augusta Ventures to pursue CYBG, said it has “engaged All Square Finance to use its specialist knowledge and expertise in bringing claims against banks, and to bring hundreds more claimants to join RGL’s action against Clydesdale Bank and [its former owner] National Australia Bank”.

The case relates to tailored business loans that RGL claims the banking group mis-sold to small businesses between 2001 and 2012. RGL said its claimant group is made up of 500 members while All Square is expected to introduce up to 550 more.

RGL chief executive James Hayward said that joining with All Square means that “Clydesdale and NAB now have a bigger, stronger and more determined group to face”.

“Our case is strong and we will issue proceedings in due course,” he said.

CYBG, which is yet to receive any details of the potential claim against it, declined to comment on the collaboration between RGL and All Square.

Last year it stated that it did not accept “allegations” being made against it by RGL and was prepared to defend them “in the strongest terms possible”.

The claim against the banking group, which acquired Virgin Money earlier this month, is being put together by Garbhan Shanks, a partner at Exeter-based law firm Michelmores.
