The Security Council's Role in International Conflict: Why Small-State Diplomacy Matters

For our first Policy & Practice seminar of academic year 2024-2025 we were joined by ex-Ambassador Simona Leskovar. The ex-Ambassador talked about her own experience both in trying to get Slovenia elected to the UN Security Council, but also more broadly about her experience in the UK and within the UN. The talk included a discussion as to why small states matter in international security. We are delighted that Sir Mark Lyall Grant GCMG joined us to give a response.
