There are fears a British far-right campaigner will further inflame the anti-immigration movement here as he arrives in Ireland.
Anti-Islam Tommy Robinson - whose real name is Stephen Yaxley-Lennon - is understood to be in Dublin to make a documentary about a surge of anti-immigration protests here. He updated his followers on the Telegram website to say he was visiting Dublin as a journalist.
"Just a quick message to Irish politicians, left wing nutcase activists and ‘journalists’ in mainstream media. I invited myself to Ireland. I’m a journalist. I’ll go where I want. Just to set the record straight,” he wrote.
