Fianna Fáil will hold a special party meeting next Tuesday evening to discuss the proposed concrete block levy.

The meeting will be chaired by Housing Minister Darragh O'Brien and Public Expenditure Minister Michael McGrath.

It will then report back to the party with findings in advance of the Finance Bill, which comes before the Dáil on 20 October.

Concerns about the proposed levy were raised again this evening at the party's weekly parliamentary party meeting.

Dublin South-West TD John Lahart told the meeting that it would impact on the cost of building a home and also on major State projects.

Elsewhere, Tánaiste Leo Varadkar sought to reassure his Fine Gael party colleagues that the exact details of the concrete block levy would be worked out before the Finance Bill.

The levy should place the onus on the construction industry and not the average tax payer, he said.

Meanwhile, a Sinn Féin motion to scrap the levy was defeated in a Dáil vote tonight.

Instead a majority backed a Government counter motion with 72 TDs voting in favour and 59 against.

The Oireachtas Finance Committee has agreed to a request from Sinn Féin's Pearse Doherty to hold hearings to examine the Government's proposed concrete levy.

The Committee is expected to hear from homeowners affected by mica, the Construction Industry Federation, officials from the Department of Finance and the Society of Chartered Surveyors.
