The whole programme is devoted to the war in Ukraine.

The Ukrainian ambassador to the UK tells Sitrep that President Putins’s announcement that Russia is mobilising around 300 thousand military reservists is a sign he feels he might be losing the war. He also tells the programme that President Putin is blackmailing the international community by appearing to raise the threat of nuclear weapons.

Sitrep will also hear how the fighting is going on the ground from a reporter who’s just returned from the region around Kharkiv in the North -East of Ukraine and seen the devastation caused by the Russian invasion.

And a panel discusses the choices facing both Russia and Ukraine militarily and strategically in the months to come. Russia expert Bridget Kendall tells us that she thinks Putin may turn to targeting more of Ukraine’s infrastructure – including fuel and water - as the winter starts to bite.
