Invest in my personal fund and get a discount on Arm’s cutting edge chip technology: that was the offer allegedly made by China boss Allen Wu to some of his customers.
That conflict of interest is one of several accusations that have been levelled at Mr Wu, the chief executive of Arm China, as he battles SoftBank and the powerful Chinese private equity firm Hopu for control of the valuable unit.
After several months of quiet negotiations, the tensions burst into public view earlier this month, after Arm, the UK chip designer that SoftBank bought for £24.3bn in 2016, announced it had ousted Mr Wu, alleging “serious irregularities” and “conflicts of interest”.
