Disarmament blog: the P5 meet in London

Last week saw a major milestone in preparations for the Nuclear Non-Proliferation Treaty (NPT) Review Conference in April, when the five NPT Nuclear Weapon States met at Lancaster House in London for their ninth annual ‘P5’ conference.

Disarmament blog: disarmament in 2020

2020 is going to be a hugely important year for multilateral disarmament in Geneva. The biggest event of the year, of course, is the Review Conference of the Nuclear Non-Proliferation Treaty, which takes place in New York over April and May.

Disarmament blog: Towards a World Free of Land Mines

People stood together

The Norwegian capital Oslo is where, in September 1997, the Anti-Personnel Mine Ban Convention (APMBC) was concluded, and also where the International Campaign to Ban Landmines, and its founder Jody Williams, were awarded the Nobel Peace Prize the following year. So although the Convention is often known as the Ottawa Convention, after the city where […]

Disarmament blog: nuclear transparency in action

The three principles of disarmament are usually held to be verifiability, irreversibility and transparency. Transparency underpins the other two principles. You can’t tell whether what’s been done is irreversible unless you can verify it; you can’t verify it unless it’s transparent. As such, transparency, often in the shape of reporting by States Parties, is a […]

Disarmament blog: the Conference on Disarmament in 2019

The Conference on Disarmament (CD) adopted its Annual Report to the UN General Assembly last week. Thanks to the skilful work of the sixth and final President for the year, Zimbabwean Ambassador Taonga Mushayavanhu, this was a quicker and much less fractious process than many of us were expecting. With that, a week ahead of […]

Disarmament blog: back to school

As August turns to September, the traffic jams return to Geneva and the evenings start drawing in. People start returning from the beaches or mountains. It’s ‘back to school’ time. In fact, the disarmament community has been back at work since 29 July, when the CD resumed its 2019 session. So I feel like I’ve […]

Disarmament blog: space – the final frontier for arms control?

I spent part of last week at the Space Security Conference run by the UN Institute for Disarmament Research, which has become something of an annual fixture. It was excellent – the organisers brought together an amazing group of speakers from governments, academia, the media and industry, and I came away with a far better […]

Disarmament blog: preparing for the NPT Review Conference

The third session of the Preparatory Committee for the 2020 Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons opens today at UN Headquarters in New York. (Otherwise known as the NPT RevCon PrepCom; while we work tirelessly against the proliferation of nuclear weapons, we’re quite happy to proliferate jargon.) Over the next […]

Disarmament blog: Looking back at the UK’s Conference on Disarmament Presidency

Four weeks ago, the UK assumed the rotating Presidency of the Conference on Disarmament. Today, we hand it over, with our best wishes, to the US. It’s been an intense four weeks. During the High Level Segment we heard from 30 Ministers over five plenary meetings. We presided over eight working formal and informal plenary […]

Disarmament blog: Taking on the Presidency of the Conference on Disarmament

The Presidency of the Conference on Disarmament rotates alphabetically amongst its members, who each take a turn for four weeks while the Conference is in session. That means that, over the 24 weeks of each year’s session, six countries are asked to take the chair. This week, the UK picked up the baton from Ukraine […]
