Trevor Lunn said: “The Westminster results in Northern Ireland are a victory for positive politics.
“The fact that Alliance did so well shows that people want politics that works for all and they want a shared future. These election results are a genuine vote for progress and for the work of the institutions here.
“This is a new era in politics in Northern Ireland, ushered in by Naomi Long and her excellent victory in East Belfast.
“The elections are also a vote against the unfair cuts that the Conservatives are proposing in Northern Ireland. People want stability and growth and Alliance will deliver that.”
