A candlelit vigil has been held outside the Department for Education in memory of Brianna Ghey.
Brianna, who was a transgender girl from Birchwood in Warrington, was found by members of the public as she lay with fatal stab wounds on a path in Culcheth Linear Park at around 3.13pm on Saturday.
Two teenagers charged with her murder were remanded into custody by a district judge on Wednesday.
Hundreds of mourners gathered outside the department building in central London, holding trans pride flags and placards.
A minute’s silence for Brianna was held at 7pm.
Bouquets of flowers and a sign saying RIP Brianna were left at the door of the building.
The crowd chanted: “When trans rights are under attack, what do you do?
“Stand up, fight back.”
The crowd also chanted: “Say her name, Brianna Ghey.”
Messages to Brianna were written on postcards and left outside the building.
One read: “You were too young.”
The other read: “Trans rights are human rights.”
At the end of the vigil, the attendees staged a “die-in”.
They lay on the ground and chanted: “How many of our corpses does it take for you to care?”
