Why has Russia exited the grain deal brokered by Turkey?

When the Black Sea Grain Initiative was reached last year, it was hailed as a diplomatic breakthrough – a rare instance of cooperation between Russia and Ukraine.

But now Moscow says it won’t extend the export agreement.

The United Nations and Turkey brokered the original deal and Turkish President Recep Tayyip Erdogan says he is hopeful it can be salvaged.

But trust in his role as a neutral mediator may not be as high as it once was.

So how much politics is at play?

And what does it mean for global food supplies?
