With Russia and the US reportedly coming up with a 28 point plan to bring an end to the War in Ukraine, The Crisis Room team dissects whether this plan has any chance of leading to a just and lasting peace - or if, in reality, it's simply a surrender.

The team reveals how backchannel negotiations work: why intelligence bosses can sometimes be more effective negotiators than diplomats, and why this so-called peace plan fails on several crucial fronts.

Later, Amber and Marc P recall their dealings with Saudi Arabia as the team analyses the Crown Prince's controversial visit to the White House. Should Mohammed Bin Salman be treated as an invaluable ally to the West, or a pariah after the killing of journalist Jamal Khashoggi? They explain why the equation for Western governments and world leaders isn't quite that straightforward.

Plus Mark tells us what defines a "spy ship" - and whether we should be worried by reports that a Russian spy ship has returned to British waters.
