UNITED IRELAND ‘NO’ IF TAXES RISE Only a third of voters in the Republic would support a united Ireland, if it meant paying more tax. A Behaviour and Attitudes survey for the Sunday Times has found just 32 per cent would back Irish unity if that meant higher taxes. The figures changed dramatically in a situation where a United Ireland led to lower tax levels. In that case, 72 per cent said they were in favour of uniting the island of Ireland.
