Martin Luther King Jr's granddaughter gives rousing speech at anti-gun rally

The granddaughter of civil rights activist Dr Martin Luther King Jr made a surprise appearance at the March for Our Lives rally in Washington DC on Saturday (local time).

Yolanda Renee King, 9, invoked her grandfather's iconic 'I Have a Dream' speech when she spoke to the crowd of thousands who were there to demand an end to American gun violence.

"I have a dream that enough is enough, and that this should be a gun-free world," she said to cheers. "Period."

The youngster then went on to lead the crowd in a chant calling for this generation to be the one to make change. She appeared onstage holding hands with Jaclyn Corin, a 17-year-old survivor of the Valentine’s Day school shooting in Florida.

Dr King delivered his famous speech at the March on Washington for Jobs and Freedom in 1963 to protest against racism.

Almost one million people participated in the March for our Lives across the United States, which was organised by the teenage survivors of the shooting at Marjory Stoneman Douglas High School in Florida.

A gunman killed 17 students and staff members on February 14, sparking a nationwide movement for tighter gun control restrictions.
