Parkland school shooting survivor Cameron Kasky has given a passionate speech at the March For Our Lives demonstration in Washington DC.

His speech was one of many from students who were affected by February's mass shooting.

Addressing a crowd of tens of thousands the teenager said "Politicians, either represent the people or get out".

"The people demand a law banning the sale of assault weapons, the people demand we prohibit the sale of high capacity magazines, the people demand universal background checks".
