Businessman and political watcher Alex Tsakumis is doubling down on his allegations Mayor Ken Sim was driving drunk and Vancouver Police knew it. In a response to Sim’s defamation lawsuit Tsakumis says the mayor has a history of intoxication while attending events and social media posts had been made in the public interest. The Statement of Defense is filed on behalf of Tsakumis and former ABC campaign manager Kareem Allam. A police review of the situation had found no basis to the claims.
