It is an honour and privilege for me to be appointed Head of the UK Delegation at this time. The OSCE sits at the heart of efforts to resolve the Ukraine crisis, and over the coming months and years will have an important role to play in strengthening security and stability in Europe

I look forward to working with international partners to uphold and promote the principles upon which the OSCE is founded and to which the UK is strongly committed. I will be working for the greatest possible OSCE success in preventing and resolving conflict, supporting rights and freedoms, and building strong, healthy societies so that all Europeans may enjoy sustainable peace and security.
