Reclaim the Night North March, protesting against violence against women: organised by the NUS women's campaign. Meeting 6pm on Sat 1st March at Sackville Street, more details in the link.
I think I'd heard of transfolk having hassle at these events in the past, so it's worth noting that the organisers specifically mention that transwomen are welcome. There's a mens/support march at the same place and time, which is also good to see.
