Stephen Jones and Neil Mackenzie headed up two of the four estate agency firms involved in the cartel, three of which were fined £600,000 earlier this year.

CMA says it has started proceedings that will see Stephen Jones and Neal Mackenzie barred from running businesses, for up to five years.

Estate agencies Michael Hardy, Prospect and Richard Worth will jointly pay the fine but a fourth guilty company, Romans, escapes a fine after reporting the carterl to the CMA.
