Biodiversity Beyond National Jurisdiction Bill

Debate between Andrew Rosindell and Emily Thornberry

2nd reading
Thursday 16th October 2025 Commons Chamber

[Andrew Rosindell (Romford) (Con)]

I thank the Minister for her explanation of the Bill. It is an important piece of legislation, and I thank her for acknowledging that it started under the previous Government. I hope there will be a consensus, but there are many questions to be answered, and we need to go into this legislation in a lot of detail to ensure that there are not unintended consequences.

Nobody in this House doubts the importance of protecting our oceans. The high seas belong to us all, to every nation on this planet, and the United Kingdom, as a proud seafaring nation and a world leader in natural sciences with no less than 16 overseas territories spanning—for now at least—all five of the world’s major oceans, has always led the world in safeguarding them. The protection of our oceans is one of the defining challenges of our age. Two thirds of the world’s oceans lie beyond the jurisdiction of any single nation, and those waters are home to a vast array of life that sustains the planet’s ecosystems.

Britain depends on the seas for our trade. They have been a moat for our national security and are our bridge to the wider world. We therefore have not only a moral duty to protect them but a strategic one. One of the core values of the small c conservatism that I believe in, as the name suggests, is to conserve things that truly matter. That applies not only to our institutions and our way of life here in these islands, but to the preservation of our green and pleasant land and, in this case, that of the marine biodiversity, so that we can hand on to our descendants the natural beauty that I know we all cherish. That principle is certainly not in question today by anyone in this House of any party.

Nowhere is our record clearer than in the crown jewel of our leadership on the environment that is the blue belt programme. Through it, the United Kingdom and our overseas territories have created over 4.4 million sq km of marine protected areas from the South Atlantic and the Pacific to the Indian ocean. These waters safeguard king penguins on the Falkland Islands, green turtles on Ascension Island, grey reef sharks on the Pitcairn Islands and countless other species across the globe. I have had the privilege to visit the Falkland Islands and Ascension Island and see the amazing biodiversity that we are responsible for, and the oceans around those territories are vital to protect. The blue belt is one of the largest networks of protected ocean on Earth, and it exists because of British leadership alongside the Governments of the British overseas territories. We granted those creatures and their habitats protection from exploitation by others, from industrial fishing fleets and from countries that would plunder our resources without a second thought. That is something this nation should be immensely proud of.

[Emily Thornberry (Islington South and Finsbury) (Lab)]

I am listening carefully to what the hon. Member is saying, and he is absolutely right on the blue belt. Does he therefore regret that in all the debates we have had about the Chagos Islands, the Conservatives have not raised the importance of the conservation of the fish stocks and the biodiversity around those islands?

[Andrew Rosindell]

The chairman of the Foreign Affairs Committee is, I am afraid, incorrect. We have raised those issues on many occasions, and I have personally raised them on countless occasions over the years. Before too long, the right hon. Member will hear a bit more about the Chagos Islands and the importance of protecting marine stocks and biodiversity in that part of the world.

Despite what has been said today, I fear that at this stage the Government are riding roughshod over that record and undermining those very principles through their abject surrender of a marine protected area. The British Indian Ocean Territory might look like a scattering of remote atolls in a far-flung region of the planet, but they are home to 640,000 sq km of ocean—one of the most pristine marine ecosystems on the earth, an area of ocean the size of France. Within it live more than 1,000 species of fish and over 200 species of coral.

I had the opportunity to see it for myself in 2019 when I visited the Chagos islands, in particular the atoll of Peros Banhos, where I was greeted by the wonderful Chagossian coconut crabs, as I jumped out of the dinghy and walked on to the beach and into the uninhabited island—where we shamefully forced the people to leave their homes all those years ago and refused to allow them to return. Its waters shelter seabirds, turtles and dolphins. It is an environmental treasure that the world envies and that Britain has rightly protected over so many years.
