A man who poured glitter over UK Labour leader Keir Starmer before his speech at the party conference said he knows his actions "crossed the line".
Yaz Ashmawi has admitted to tipping glitter over the Labour leader and grabbing him just as he was about to begin his set piece speech in Liverpool on Tuesday.
Speaking to the Politics Uncensored podcast on Fubar Radio, Mr Ashmawi said he took responsibility for what he did and apologised for making Mr Starmer feel unsafe.
"The thought that, even for a moment, he felt that he was in danger is horrible to think about.
"I think it is absolutely fine to pour glitter on someone and to go onto the stage. I just think it is physical contact that crossed the line there," he said.
Asked whether he would like to apologise to Mr Starmer, he said: "Yes, absolutely. I'm sorry for doing that."
Merseyside Police confirmed it arrested a 28-year-old man from Surrey on suspicion of assault, breach of the peace and causing public nuisance following the stunt.
The police said the man - who Mr Ashmawi confirmed is him - had been bailed pending further inquiries. Mr Ashmawi told the podcast he was kept in a cell for 22 hours after his arrest.
He belongs to a group called People Demand Democracy.
After throwing the glitter, Mr Ashmawi shouted "true democracy is citizen-led".
He continued: "politics needs an update", "we demand a people's house", "we are in crisis" and "our whole future is in jeopardy", as he was wrestled to the ground.
Mr Ashmawi said he used some chairs to hoist himself up and he "hopped" onto the stage where Mr Starmer was standing waiting for the applause to subside before addressing the crowd.
"The thing is, I put my hand on his arm and touched him... politicians, they get a lot of death threats and they have a need to feel safe and I compromised that in that moment by touching him.
"If Mr Starmer felt that he was threatened... I take responsibility for that, I want to take full responsibility for my action," he said.
Mr Starmer pushed Mr Ashmawi away from the microphone with his right arm before security arrived.
After removing his jacket, the Labour leader said "if he thinks that bothers me, he doesn't know me", before beginning his speech with glitter on the shoulders of his shirt.
In interviews after the incident, Mr Starmer said he checked his wife who was in the front row of the conference hall, was all right before continuing.
He told Sky News that the incident "could have been a lot worse", with questions raised about the level of security in place for the politician who could be the next prime minister in the UK.
Since the incident, the party has been advertising t-shirts for sale with the slogan: "Sparkle with Starmer".
