This update adds the poll published by Ipsos MRBI in the Irish Times on 20 January. This poll put Fianna Fáil in pole position (25 per cent), but the difference to Fine Gael (on 23 per cent) is much smaller than in the Behaviour & Attitudes poll published at the weekend, which ranked Fianna Fáil at 32 and Fine Gael at 20 per cent.
