Thousands are expected to descend onto College Green in Bristol this weekend, as a Black Lives Matter (BLM) protest hits the city.
It follows the death of George Floyd in the US last week, sparking worldwide demonstrations.
He died whilst under police custody in Minneapolis, after a white officer knelt on his neck for nearly nine minutes.
Videos taken by witnesses capture Floyd begging for his life, saying "I can't breathe" before losing consciousness.
The past 10 days have seen uprisings - as well as some riots and looting - across America. Last week, Donald Trump's comments on the protests were marked by Twitter with a warning, after violating rules about "glorifying violence".
The tweet included the words "when the looting starts, the shooting starts" - thought to reference a quote from late Miami police chief Water Headley in 1967.
He was notorious for violent confrontations with black protesters at the time.
The US President later denied he was issuing a threat to citizens.
BLM says it's a global organisation that "builds power to bring justice, healing and freedom to Black people across the globe".
Bristol's event - arranged by local BLM campaigners - so far has over 4,000 people "going" on Facebook, with another 8,500 "interested".
Speakers are expected to start at 13:00 GMT, with the protest moving through the city from 14:00 GMT.
One of the organisers, Yvonne Maina, told us what the demonstrations are aiming to achieve: "We're really hoping to spark the conversation of how the UK can really improve the way we educate people on racism ... how people react to being called out about racism.
"This conversation cannot end here, on this Sunday, we need to keep it moving".
She also said protesters will respect social distancing, urging anyone with Coronavirus symptoms to support from home instead:
