Amazon founder Jeff Bezos is expected to sell more of his stake in the business, after offloading around £200m worth of shares last week.

The business founder could sell as many as 8m to 10m shares, valued at around £800m ($1bn), according to a CNBC report.

According to the filings, Bezos’s transactions were marked as contributions to non-profit organisations, but it remained unclear who received the donations.

Bezos currently owns around 988m Amazon shares, amounting to an almost 10% stake in the company.
