Mícheal Martin described it as a "propaganda designed to promote Fine Gael"

Pressure is mounting on the Taoiseach to disband the Government's Strategic Communications Unit.

The SCU - which has come under scrutiny over the past week - is now being reviewed by the Secretary General of the Department of the Taoiseach at Leo Varadkar's request.

Sinn Féin plans to bring a motion to disband the so-called 'spin unit' - describing it as a "highly expensive PR Unit, paid for by the taxpayer for the benefit of the Taoiseach and Fine Gael".

The leader of Fianna Fáil Michael Martin suggested the unit is dangerous and not good for democracy.

Speaking on The Last Word, he said: "I think it represents a fundamental blurring of the lines - the politicisation of the civil surface.

"It's a propaganda designed to promote Fine Gael, and to make the Government indistinguishable from Fine Gael."

Independent Minister Katherine Zappone also has concerns about the unit, and welcomed the fact that it's being reviewed.

"I welcome the Taoiseach's comments [...] that everything is on the table in relation to that review," she added.
