The Social Democrats have accused RTÉ of State censorship ahead of tomorrow's debate.

RTÉ are excluding four of the eight political parties from the leader's debate.

Speaking at the launch of the party's education policy, Social Democrats co-leader Stephen Donnelly criticised RTÉ for being part of the cartel protecting the establishment:

He said: "We're trying to get a message out on a fraction of the resources available. When the State broadcaster is essentially engaged in censorship of four of the eight political parties three days before the debate, it makes it very difficult.

"So, we're fighting against the State broadcaster's position on protecting the establishment.

"It's hard enough to challenge the cartel, without RTÉ protecting them as well."
