Labour TDs across the country will receive 100,000 post cards in the coming weeks warning them to axe the property tax.

The Campaign Against Household and Water Taxes launched its postcard campaign outside Labour Headquarters in Dublin this morning.

The campaign also said it would be mobilising large contingents to take part in the anti-austerity march on Saturday which is being organised by the ICTU.

"Government can be sent into crisis"

18 Labour TDs are in Dublin - and 9 others in the other 4 key cities - are to be targeted.

The campaign says each one will be landed with thousands of postcards on their doorsteps from their constituents, collected up by the local campaigns against home taxes.

Campaign Spokesperson Councillor Ruth Coppinger says Labour must reverse the measure or it will be hit at the polls.

"The campaigns in these cities will building huge political pressure on TDs with the postcards, public meetings and protests" she said.

"The message will be : back off deduction of the tax or watch your vote collapse in local and Euro elections next year. Combined with a boycott of hundreds of thousands of tax forms in March, this government can be sent into crisis" she added.
