The parade leaves from Waterside Railway Station to Guildhall Square on Saturday, August 25, at 2 pm.
The party’s leader on Derry City & Strabane District Council said:
“Sinn Féin is proud to support the Foyle Pride march which takes place this Saturday. We will be assembling at the Waterside Railway Station at 1.45pm.
“I am calling on the people of Derry to come on to the streets and demand full equality for our LGBTQ brothers and sisters.
“In 1968, the people of Derry took to the streets to march for civil rights.
“Fifty years on, there is still more to be done, including the extension of marriage equality across the island of Ireland.
“Pride is first and foremost a protest, but also a fantastic opportunity to send a loud and colourful message that Derry stands against inequality and discrimination,” she added.
