Yay someone else remembered
Even John Armstrong in the Herald was saying no-one could recall a PM being evicted before, but NZPA’s Ian Llewellyn confirms I am not imagining things by saying “It brought back memories of another Labour prime minister David Lange and Opposition leader Jim Bolger both being removed in 1987, the pair leaving the House arm-in-arm.”
My recollection also is that Lange and Bolger thought it was hilarious they got evicted simulteanously.
