HIV campaigners dumped manure in front of Ukip's south London office in protest over party leader Nigel Farage's "offensive" comments about the virus.
Activists from ACT UP were pictured kissing next to the manure in Croydon yesterday for World AIDS Day.
A protest banner in the background read: "What goes around comes around. Solidarity on World AIDS Day. #UkipStinks’".
The group said it was showing its opposition to Mr Farage's suggestion that people living with HIV should be barred from entering the UK.
Group spokesman Gary Hunter said: “We’ve had enough of Ukip’s misinformation and offensive attacks on minorities.
"We wanted to show Farage that people living with HIV aren’t going to take his bull**** any longer – so we’ve returned it.
"The vile crap that Ukip keeps spreading stigmatises and ostracises people living with HIV, gay people and immigrants.
"We thought this steaming pile of muck was a great representation of what we, as HIV-positive people, think of Ukip’s agenda.”
In an interview with Newsweek Europe, Mr Farage said his preference for the type of immigrant he would support moving to the UK was "people who do not have HIV".
He later tried to defend his comments, saying he would also ban "people with tuberculosis too".
ACT UP spokesman Mario Azeitona said: “Ukip keep saying that they speak for ordinary British people, but the vast majority of people totally reject their poisonous views.
"We are sending a message back to them that they do not represent the Britain most of us know – based on respect, solidarity and community."
Ukip have been approached for a comment.
