Russia knows our weaknesses. But do you?   

A major five-part series from Sky News and Tortoise which imagines how a Russian attack on the UK could play out – and invites real-life former ministers, military chiefs and other experts to figure out how to defend the country.   

Written and presented by Sky News' security and defence editor, Deborah Haynes.

This is Deborah's second podcast series for Sky News. In her first series, Into The Grey Zone, Deborah explores the murky evolution of warfare.

What do assassinations, cyber hacks and disinformation have in common? They're all weapons used by states against each other in a grey zone of harm under the threshold of war, but could be just as dangerous if ignored.
