The February 2020 general election in the Republic of Ireland sent shockwaves through the country's political system. Sinn F�in, ahead of all other parties in terms of first preference votes, secured its place as a potential coalition partner, a role it has been playing in Northern Ireland since the start of the century. This result not only disrupted the two-party system, it also questioned a narrative that had cast Sinn F�in as an outlier in the political mainstream. However, the prospect of this all-Ireland, radical left and former Provisional IRA associate being in government raises many questions: what does the success of this all-Ireland party say about the prospect of reunification? Can a party over which the shadow of paramilitaries still lingers be fully trusted? And are the radical changes that the party advocates in areas such as housing, public health and taxation a compelling alternative? These are the questions that this book sets out to address.
