It’s three months since the 29-year-old journalist Lyra Mckee was killed in a riot in Northern Ireland. Her death shocked the world and there were calls for politicians in Northern Ireland to unite. But since then the assembly in Stormont still hasn't sat.

We went to Londonderry to speak to Lyra’s partner Sara Canning, who took us on a tour and introduced us to other campaigners.
