Both Labour and the Liberal Democrats ruled out coalitions with UKIP. Ruth Davidson, leader of the Scottish Conservatives, asked about a deal with UKIP in the Scottish leaders' debate, replied: "No deals with UKIP." She continued that her preference and the Prime Minister's preference in a hung Parliament was for a minority Conservative government. UKIP said they could have supported a minority Conservative government through a confidence and supply arrangement in return for a referendum on EU membership before Christmas 2015. They also spoke of the DUP joining UKIP in this arrangement. UKIP and DUP said they would work together in Parliament. The DUP welcomed the possibility of a hung Parliament and the influence that this would bring them. The party's deputy leader, Nigel Dodds, said the party could work with the Conservatives or Labour, but that the party is "not interested in a full-blown coalition government". Their leader, Peter Robinson, said that the DUP would talk first to whichever party wins the most seats. The DUP said they wanted, for their support, a commitment to 2% defence spending, a referendum on EU membership, and a reversal of the under-occupation penalty. They opposed the SNP being involved in government. The UUP also indicated that they would not work with the SNP if it wanted another independence referendum in Scotland.
