Tesco is understood to be on the verge of ditching its auditor PwC following the accounting scandal which saw the grocer report a £263m profits overstatement.
According to The Independent, Tesco board members are furious with PwC’s response since the fallout.
A new auditor is being lined up for 2016 but sources told the paper this could be moved forward to next year.
Tesco chief Dave Lewis was forced to issue a profit warning just weeks into his new role after a whistleblower brought to his attention the accounting scandal.
An investigation by Deloitte and Freshfields found that half-year profits were overstated by £263m and that the misreporting spread further than that time frame.
The investigation has since been taken up by the Serious Fraud Office.
Since the initial report, Deloitte has been hired by Tesco to work with its accountancy department to avoid the misreporting happening again.
Tesco has worked with PwC since 1983.
Tesco and PwC declined to comment.
