Australia’s most populous state, New South Wales, has lodged a legal application to stop a Black Lives Matter protest occurring in Sydney, state Premier Gladys Berejiklian said on Friday.

Thousands of people have pledged to attend a protest organised in Sydney on Saturday following the police killing of George Floyd, an unarmed Black man.

The protest had secured permission as it originally planned to have fewer than 500 people present.

But Berejiklian said when it became clear that thousands planned to attend, the legal application was made to the state’s Supreme Court.
