Behind the demonstration is the Stop Trump UK Coalition, a group consisting of 50 organizations, including climate activists, anti-racists and pro-Palestinian activists.
Some protesters had brought Trump balloons, which have been seen at Trump-critical protests before, depicting a screaming president in a diaper.
We want our government to show backbone and have some pride and represent the enormous disgust at Donald Trump's policy that exists in the UK, says Zoe Gardner, political commentator and one of the organizers behind the protests, to BBC.
Demonstration participants who The Guardian has spoken to say that their participation, in addition to Trump, is also about showing dissatisfaction with Prime Minister Keir Starmer and his policy.
Whatever the public can do, even if it's about joining a protest and just marching and raising their voices, however small-scale it may be, is better than nothing, says a female art teacher from southern London, to The Guardian.
The protesters gathered in central London on Wednesday afternoon and then marched towards Westminster.
