Mayo homeowners, whose properties are impacted by pyrite damage, will be represented on a new working group being set up to advise Government on altering and changing the current remediation scheme.

Following a rally in Dublin yesterday attended by thousands of people - mainly from the West and northwest region - a Sinn Fein motion calling for 100% redress for homeowners was passed in the Dáil last night.

The Housing Minister Darragh O'Brien said the existing scheme will be expanded, but stopped short of announcing 100% compensation.

The current scheme, open to homeowners in Mayo and Donegal, only provides for 90% redress.

Minister O'Brien is setting up a working group to examine the scheme, and it will include homeowners impacted by pyrite and mica.

He wants them to report back by late July.
