Britain’s King Charles three has been heckled by an Aboriginal lawmaker after he arrived in Australia for the first visit to the country by a reigning monarch in more than a decade.

Charles, who is on his first royal tour since announcing his cancer diagnosis in February, was confronted yesterday after completing an address to Australia’s Parliament in which he urged stronger action against climate change.

Senator Lidia Thorpe yelled that the king committed genocide against their people.

The country has had de facto independence from Britain since 1901, but remains a Commonwealth realm with the British monarch as the head of state.
