MySale chief executive Carl Jackson is interested in buying shares worth up to £3m in the troubled etailer.

MySale, whose investors include Arcadia tycoon Sir Philip Green and Mike Ashley’s Sports Direct, floated in June but this week issued a profit warning after trading slowed in its core Australia and New Zealand markets.

Jackson founded MySale with his brother Jamie, and would therefore be deemed part of a concert party under Stock Exchange rules and would need special dispensation to buy more shares.

The concert party already controls more than 34% of MySale’s shares.

This week’s profit warning led to MySale losing almost half of its value but Jackson’s interest in buying more shares gave the stock a fillip.
