Hello, I'm Katya Adler, host of the Global Story podcast from the BBC.
Each weekday we break down one big news story
with fresh perspectives from journalists around the world.
From artificial intelligence to divisive politics tearing our societies apart
from the movements of money
and markets to the human stories that touch our lives,
we bring you in depth insights from across the BBC and beyond.
Listen to the Global Story wherever you get your BBC podcasts.
Hello and welcome to NewsHour.
It's coming to you live from the BBC World Service studios in central London.
I'm Tim Franks.
It is perhaps not a surprise.
It is still stunning to look around
and see the number of people who are saying this is a historic shift.
What Donald Trump has said and done in the last 24 hours about a Ukraine,
Russia peace deal, how all this presages a huge change,
not just for Ukraine, but for the whole of Europe and the way we think about big power politics.
Some say these changes are comparable to events leading up to
and then the aftermath of World War II.
