Support for Fine Gael and Labour has slumped in the latest opinion poll of the general election campaign.

The Red C tracking poll published in the Sunday Business Post shows support for Taoiseach Enda Kenny's party has fallen by three points to 28 per cent and Joan Burton saw her party's backing drop two points to 8 per cent.

With less than two weeks to election day, February 26th, Sinn Féin will be happiest with the poll as its support has risen by three points to 20 per cent, making it the second most popular party in the study.

Fianna Fáil gained one point, rising to 18 per cent, and Independents/others have the backing of more than a quarter of the electorate, with support rising one point to 26 per cent.

The poll comes after the party leaders held their first debate of the campaign on Thursday and ahead of a second leaders’ debate on Monday night.
