Agents who have given notice to the portal to quit are sent one - and sometimes several - emails on their final day giving them one last chance not to drop Rightmove.

Key campaigning groups make joint appeal to industry to work collectively and force Rightmove to charge fair fees and re-balance the relationship.

Letting agent calls on colleagues across the UK to sign her petition after the portal revealed it is eligible for the Covid Corporate Financing Facility.

Rob Sargent of estate agency The Acorn Group submits himself to hard questioning over his motivations to set up and fund a campaign to persuade Rightmove to change its business and pricing.

While existing estate agencies were recently given a 33% discount, firms joining the firm are to be given a full discount until the crisis is over.

Acorn Group dedicates half a dozen staff to the cause as CEO Rob Sargent sees a once-in-a-lifetime opportunity to weaken the portal's power.

Agent claims to have caught out portal by using a private email address to register for Property Alerts, an address which has now been used by Charcol to prospect for mortgage business.

The Negotiator put this, and many other key questions preying on agents minds at the moment to Zoopla’s commercial head Andy Marshall.
