Lord Christopher Monckton has slammed Port Adelaide Football Club for its decision to withdraw its venue for his speaking tour, blaming the club's decision on pressure from activist group GetUp.

In an exclusive Crikey interview, Lord Monckton laid the blame for the withdrawal squarely at the feet of GetUp who he accused of orchestrating an online campaign to silence him. He expressed supreme displeasure at the cavalcade of venue cancellations on his east coast tour following negative publicity over his use of an on-stage Nazi swastika.
