The fund operator KKR is among a group of financial investors that are set to make offers for the fitness chain ahead of a deadline on Thursday, Sky News said.

Pure Gym's sale comes over a year after it announced, and later cancelled a 190 million-pound initial public offer of shares due to "challenging IPO market conditions".

The chain's major shareholder CCMP Capital Advisors has controlled the chain since 2013 and overseen a period of growth and expansion.
