The Taoiseach has made a televised address on the fiscal treaty in which he called for a Yes vote in the upcoming referendum.

Enda Kenny said a Yes vote would be the best way of ensuring growth in investment in jobs.

He said only a Yes vote will give Ireland guaranteed access to Europe's permanent rescue fund - the European Stability Mechanism - should Ireland ever need it.

To ensure RTÉ provides balanced coverage, the Taoiseach was afforded time to respond to Gerry Adams, whose leader's address to the Sinn Féin Ard Fheis was televised yesterday.

However speaking on RTÉ's The Week in Politics, Socialist Party leader Joe Higgins said the treaty should be scrapped.

Mr Higgins said austerity was failing across Europe and argued that the treaty would institutionalise it.

Elsewhere, Independent TD Shane Ross has declared that he will be calling for a No vote in the referendum.

Deputy Ross has said that he will vote No in order to postpone a decision on the treaty, until details of a proposed agreement on economic growth in Europe are finalised.

Meanwhile, three opinion polls published this morning all suggest that the Yes side is leading.

The polls were carried out by Behaviour and Attitudes for the Sunday Times, Millward Brown Lansdowne for the Sunday Independent, and Red C for the Sunday Business Post.

All suggest that if the referendum were held today, it would be passed.
