Thank you, Madam Deputy Speaker, and welcome to the Chair.

May I warmly congratulate the Defence Secretary on his new role, and strongly endorse the comments he made about Britain’s armed forces? My own regiment has recently been on the frontline in Estonia, and I want to strongly endorse the words he used. I also endorse the advice he gave to new Members sitting on these green Benches. I first sat on these green Benches—on the Government side—37 years ago, and I strongly agree with what he said. I feel that sense of honour and privilege every day in this House.

I had hoped to start by welcoming the Foreign Secretary to his place. I wanted to wish him well in discharging the immense responsibilities of the office he now holds. I have to say that I was dismayed to hear the Foreign Secretary answer questions on the “Today” programme this morning that should more properly have been answered in this House—a view that I believe Mr Speaker shares. Nevertheless, I have no doubt that the Foreign Secretary will be very well served by the outstanding civil servants at the Foreign Office. I want to express my gratitude to our ambassadors and high commissioners around the world. On overseas visits throughout my tenure, I was superbly served and looked after. I also want to thank the outstanding young officials who worked in my private office.

I should like to pay a special tribute to my noble Friend Lord Cameron of Chipping Norton. He demonstrated clear strategic thinking about how British foreign policy needed to adapt to the world as it is today and injected real energy into British diplomacy. I hope the whole House will acknowledge that to persuade a former Prime Minister to serve as Foreign Secretary was a real benefit to our country. It was also a pleasure to serve alongside the former Members for Berwick-upon-Tweed and Macclesfield, who I am very sorry are no longer sitting alongside me on the Front Bench. They were both superb Ministers, who worked diligently at the Foreign Office.

I cannot recall a more perilous period in international affairs. I entered the House of Commons just two years before the momentous fall of the Berlin wall, which precipitated the demise of the Soviet Union and the consequent end of the cold war. It is difficult to overstate, having lived with the terrifying spectre of nuclear confrontation, the collective relief we all felt. Yet the world is once again in the grip of a galloping escalation of tensions and dangers, where the international institutions created on the heels of the second world war to defend our values and protect mankind are being undermined, the narrow nationalism that so disfigured our continent is once again rearing its destructive head, and despots and dictators increasingly ride roughshod over democratic freedoms and the rules-based order.

Putin’s brutal and illegal invasion of Ukraine has brought war once again to the European continent. The Israel-Gaza conflict is devastating and risks regional conflagration. Poverty and debt stalk the global south. Yet covid taught us that no one is safe until we are all safe, while climate change is the greatest existential threat of our time. Never have we faced dangers so grave when our fates are so closely entwined. So at the very time when we need an international rules-based order to tackle these common threats—climate change, migration, terror and pandemics—we are more fragmented than ever. Divisions are hardening and debate is coarsening.
