Former Cape Town mayor and current minister Patricia de Lille, and others, reveal explosive details about Tony Leon's lobbying, igniting a political storm over Resolve Communications' influence in government.

Former Cape Town mayor Patricia de Lille has become the latest senior political figure to lift the lid on Resolve Communications’ efforts to secure access to government, revealing that Tony Leon lobbied the City of Cape Town on behalf of Uber.

This while the public relations firm also played a role in the city’s communications campaign during the height of its drought crisis.

De Lille's account, backed by Brett Herron, her transport mayco member at the time, showed Resolve was opening doors for its clients in DA-run governments as far back as a decade ago.

Their disclosures follow similar claims by former DA leader and axed agriculture minister John Steenhuisen, former environment minister Dion George and ActionSA national chairperson Michael Beaumont.
