The wife of Martin & Co founder Richard Martin, who is now the chairman of The Property Franchise Group, has cashed in some of her shares.

Kathryn Martin yesterday sold 810,000 at 138.6p, raising £1.22m.

Following this sale, she and her husband between them have a total interest in 10,189,950 shares, representing in total approximately 39.5% of the company’s issued share capital.

Richard Martin, who formerly worked in local newspaper sales, founded Martin & Co in 1986 as a single-office letting agency in Yeovil, Somerset.

In 1995, he decided to turn it into a franchise operation, with a vision of centralising some of the admin processes for agents, and planning to grow the business without recourse to the banks.

Yesterday was not the first time that the Martins have profited from his remarkable foresight. At the time of Martin & Co’s £15m flotation on the stock market in 2013, he and his wife owned 95% of the company.
