British anti-trans rights activist issues John Pesutto and leadership team with defamation concerns notices

The context:

The British activist, who also goes by pseudonym Posie Parker, spoke at a "Let Women Speak" event outside Victorian parliament in March that was gatecrashed by neo-Nazis, who joined the anti-trans rights demonstrators and repeatedly performed the Nazi salute.

MP Moira Deeming's involvement in the "Let Women Speak" rally led to her suspension and eventual expulsion from the Liberal party.
