Boohoo has demanded that Revolution Beauty explains why it handed shares worth around £2m to a group of senior executives.
The fashion giant, which holds a 26.6% stake in the company, has reacted strongly to the news that the shares were awarded to chief executive Bob Holt, chief financial officer Elizabeth Lake and 16 other members of the management team for free.
Boohoo has called for the business to publish the terms of the move together with any award letters issued to the relevant individuals on its website without delay.
