Stephen Hazell-Smith (Chairman 2005-2009) PLUS Markets Group was a UK electronic stock exchange based in London for small cap companies.

The group gained the gold standard recognised investment exchange (RIE) licence in July 2007 but struggled to make much headway against the dominant LSE.

Although it did host some well-known names, including Arsenal Football Club it failed to break even and the group eventually got into financial difficulty in 2012.

[11] PLUS Markets Group was initially run by Simon Brickles, formerly Head of AIM at the London Stock Exchange.

In 2009 Brickles and Hazell-Smith stepped down and were replaced by Cyril Theret, formerly the business development director at PLUS, and Giles Vardey as chairman.
