When the Taoiseach Simon Harris called a snap election for 29 November, Ireland’s electricity board asked political parties not to put election posters on telegraph poles. They might as well have asked them to take the time off on holiday. As I drive through the Irish countryside on my way to County Cork, I notice plenty of posters on poles, but the usual suspects – Fianna Fail, Fine Gael, Sinn Fein and Labour – are now joined by a new force in Irish politics – a grouping dedicated to a punchier, more populist, anti-immigration and pro-family agenda.
