Sinn Féin has surged in popularity while the three Government parties have lost support over the last month.

That's according to a new political poll from Behaviour and Attitudes conducted on behalf of the Sunday Times, which sees Mary Lou McDonald’s Sinn Féin open up a 10-point lead over the next most popular party, Fine Gael.
