David Crisafulli has launched a stinging attack on Steven Miles, claiming the Deputy Premier doesn't have the "intellectual capacity" to be an "attack dog" amid an ongoing war of words around the rollout of the COVID-19 vaccine. The Opposition Leader also hit out at his federal counterparts, saying they were being childish and making unhelpful comments. "We are increasingly becoming concerned with the vaccine rollout, the messaging, the prioritisation and the squabbles between Canberra and Brisbane," he said. "Quite frankly it's got to stop." Queensland Leader of the Opposition David Crisafulli didnât hold back, calling Steven Miles an embarrassment to every Queenslander. Picture: NCA NewsWire / Dan Peled
