With bids due this week, it is likely that SEP would sell its stake to a sovereign wealth fund or pension fund rather than another private equity investor, the Telegraph said, citing a person familiar with the matter.

Goldman Sachs declined to comment.

Bidders could include Baillie Gifford, the pension fund manager which recently invested in food-delivery startup HelloFresh, along with Singapore's Temasek Holdings and Japan's Softbank Group Corp, the Telegraph reported.

Temasek Holdings declined to comment.

SEP, Baillie Gifford and Softbank could not be reached for comment outside regular business hours.
