Australia is a remarkable country with incredible technical and physical resources and a capacity to be a world leader in renewables.

Australia is already a world leader in dementia research, treatment and care.

I want to see a connected and progressive future for Australia, where we harness our greatest natural resources: sun, wind, and brain power.

The British security industry has the capacity to be a world leader and it should be our shared objective to achieve this.

America is a world leader, but we should not be its policeman or ATM.

I'm not sure how a world leader reacts to the work of a clown.
