A GP known for promoting ivermectin to treat COVID-19 has agreed to temporarily suspend his registration after having his practice raided by health authorities.

Dr Mark Hobart has been a vocal critic of mandatory vaccination, as well as a director of the Covid Medical Network, urging doctors to prescribe ivermectin off-label to prevent or treat COVID-19.

But officials from the Victorian Department of Health visited his practice on Wednesday afternoon, amid allegations in the media that he provided bogus vaccine certificates and exemptions to patients without clinical need.

Supporters of the doctor, who is also under investigation by the Medical Board of Australia, live streamed the raid on Facebook.
