A "nervous" Meghan Markle has spoken out on the death of George Floyd.

The Duchess of Sussex said George Floyd's life "mattered" as she delivered an address to students at her former school.

Meghan told students at Immaculate Heart High School in Los Angeles the mass protests, which have continued to take place across the US, have been "absolutely devastating".

In a video of her virtual address, she said she was "nervous" about addressing graduates and speaking about events of the previous weeks.

She said: "I wasn't sure what I could say to you.

"I wanted to say the right thing and I was really nervous that I wouldn't or it would get picked apart, and I realised the only wrong thing to say is to say nothing because George Floyd's life mattered and Breonna Taylor's life mattered and Philando Castile's life mattered and Tamir Rice's life mattered.

"And so did so many other people whose names we know and whose names we do not know."

Widespread protests have broken out across America in the wake of George Floyd's death.

African American George Floyd died when a white police officer pinned him to the ground and knelt on his neck during an arrest on May 25.

Floyd could be heard telling officers he couldn't breathe before he died.

He was 46 years old.
