Hmmmm seems someone may have thought Christopher Pyne was a closet Labor person lol. From Wikipedia:
"Bernardi was removed from the Shadow Ministry by Turnbull after reportedly making unsubstantiated claims regarding a fellow Liberal MP in his weekly blog. He recalled an encounter with the Liberal MP at the Royal Adelaide Golf Club about 14 years ago:
In response to my question of why he joined the Liberal Party, the MP blithely responded "I live in a Liberal seat so I had to be a member of the Liberal Party to get into Parliament. If I lived in a Labor seat I would have joined the Labor Party". Frankly I was aghast at this response. Where was the conviction, the beliefs, the values that I believe should motivate our political leaders? Several follow up questions disclosed that the only motivation for his own political involvement was for him to become Prime Minister.
The MP involved was thought to be Christopher Pyne, who denied the allegations as "preposterous".[14][15][16]"
