A number of campaigners have accused the national broadcaster of bias against the anti- water charges movement over recent months.

At a march in December, an RTÉ van was daubed with the word ‘lies’.

There was also some criticism of Ryan Tubridy’s Late Late Show interview with Anti-Austerity Alliance TD Paul Murphy last month – with some viewers saying the presenter’s approach was over-the-top.

Today’s march began near Donnybrook, proceeding along a stretch of dual carriageway towards Montrose.

Protesters formed a motorcade to travel to the city centre after the RTÉ protest, which passed off peacefully

Another demonstration, in support of the water protesters jailed last month for breaking a court injunction, then took place – from O’Connell Street to Mountjoy Prison.
