Barry was involved with the Foreign Affairs Select Committee today when he grilled Alok Sharma MP and COP26 President on environmental diplomacy.
During a fascinating exchange Barry asked Mr Sharma what offers the U.K government had made to China with regards to ensuring the previous COP was a success. He then wanted to know whether the government had offered the Chinese government an agreed set of principles with regards to biodiversity.
There was also further quizzing following representations made to Barry by South African Members of Parliament with regards to the recent International Development cuts announced by the Foreign, Commonwealth and International Development Secretary, Dominic Raab, to which Barry said went to the heart of their climate challenge and urged the government to improve its delivery of climate finance against these cuts.
Finally, Barry raised the prospect of COP26 and without expecting a definitive answer asked who was the priority when it came to in person versus virtual.
