A JUST Stop Oil protester lays down in front of a Coca-Cola truck during yesterday’s Pride march in the capital.
They were then joined by others, apparently over the parade accepting sponsorship from “high-polluting industries”.
Cops carried them away at Piccadilly, central London.
Seven arrests were made.
In a statement, LGBT+ members of the protest group said: "These partnerships embarrass the LGBTQ+ community at a time when much of the cultural world is rejecting ties to these toxic industries."

They added that LGBT+ people are "suffering first" in the "accelerating social breakdown" caused by climate change.
"Pride was born from protest.
"It speaks to how far we've come as a community that high-polluting industries and the banks that fund them now see Pride as a useful vehicle for sanitising their reputations, waving rainbow flags in one hand whilst accelerating social collapse with the other."
Just Stop Oil said: "If London Pride fails to take these basic steps necessary to protect our community, we will have to consider potential escalations which may result in the disruption of Pride.
"We will also call for the entire LGBTQ+ community to join us in protest and boycott - for the safety of LGBTQ+ people everywhere."
