Outdoor apparel retailer Blacks Leisure has received approaches concerning a possible offer for the group.

The company made the announcement to the London Stock Exchange, following recent share price movement.

Blacks' shares have risen by around 40% since investors including Sports Direct owner Mike Ashley were linked with making an offer.

However, Blacks gave no details of the bidders involved.

"Discussions in relation to these approaches are currently at an early stage and may or may not lead to an offer for the group. There can be no certainty that an offer will be made nor as to the terms on which any offer might be made. A further announcement will be made in due course," the company said.
