Meanwhile a Serious Fraud Office investigation is still continuing into Quindell, which was once a darling of the AIM stock market with a valuation of more than £2 billion.
The business began to unravel in 2014 after short-sellers Gotham City Research published an infamous note labelling the firm a “golf club built on quicksand” amid controversial share trading by founder Rob Terry.
Watchstone meanwhile is fighting a court battle with Australian legal firm Slater & Gordon, which bought Quindell’s professional services division in 2015. Slater is suing for £637 million.
A KPMG spokesman said the company had “already updated our audit processes and procedures to address the areas of concern”. It added: “We regret that some aspects of our audit for the year ended December 31, 2013 did not meet the required standards... We accept the FRC’s findings that in two specific areas of the audit our challenge... should have gone further.”
