Simmons & Simmons is advising on a landmark $240 million claim brought by Abraaj Group liquidators against its former KPMG auditors in what is set to be the longest case in the 20-year history of Dubai’s DIFC Courts.

The liquidators for Abraaj are suing KPMG and KPMG Lower Gulf over alleged financial impropriety leading up to the 2018 collapse of the Middle East’s largest private equity firm.
