On the agenda for these meetings: climate change, the war in Ukraine, and the “Atlantic Declaration” – that’s the diplomatic term for Biden and Sunak’s push to renew the U.K. and America’s partnership across a host of economic and security issues facing the West.

Joining to talk about these issues as well as Britain and America’s special relationship is Karen Pierce, the British Ambassador to the United States. Pierce is one of the U.K.’s most experienced diplomats, having held an array of senior positions including ambassadorships to the U.N., the WTO, and Afghanistan; as well as directing British policy throughout South Asia, Pakistan, and Afghanistan during some key years of the War on Terror.

On this episode of Playbook Deep Dive, Pierce tells host and Playbook co-author Ryan Lizza what Sunak hopes to get out of Biden’s trip to London; how Britain and America’s relationship has changed throughout her many years of service; how the war in Ukraine is driving the two countries closer – and occasionally further apart; who Brits admire the most in our nation’s history; and what her secrets are for dealing with cagey diplomats on the other side of the bargaining table.
