George Galloway has won permission to sue Google over a speech posted online by a loyalist campaigner in Belfast.
In 2014, YouTube footage was broadcast of a loyalist protest, in which Willie Frazer suggested the former Respect MP supported terrorism.
Protests outside the Ulster Hall, where Mr Galloway was speaking, centred on his reference, that year, to Bradford being an Israeli-free area.
Mr Galloway said the loyalist’s remarks constituted a “hate speech”.
On Wednesday, a High Court judge dismissed an attempt to stop Mr Galloway serving libel and harassment proceedings on Google, which owns YouTube, at its US headquarters.
He said: “Accusing an elected politician of being a supporter of terrorism and of the people who are ‘beheading American citizens’ is going to alarm anyone so accused and to cause him distress.”
