According to the Daily Mail: City sources said Mack Brooks, which stages exhibitions and conferences for the transport, chemicals and packaging industries, has been working with PricewaterhouseCoopers advisers on a potential sale in recent weeks.
Bankers say publishing giant, the RELX group, has been toughing it out with private equity firm Inflexion in the final stages of a sale process.
Another potential buyer is Belgian private equity firm Core Equity. Any sale is likely to net Stephen Brooks a multi-million pound cash payout.
Inflexion is a PE firm previously leader of a PE consortium involved with CloserStill Media.
