Tobias Ellwood: How should the West stand up to Putin?

Russia has launched its most deadly attack on western Ukraine so far, striking a military base just 15 kilometres from the Polish border. This is being seen as a warning to Nato that, in supplying weapons to Ukraine through Poland, it risks an escalation of the war. Zeinab Badawi speaks to the senior British Conservative MP Tobias Ellwood, the chair of the House of Commons Defence Select Committee and a former soldier. He believes that Nato and the West need to change radically their stance on the Ukraine war. Does he have a clear strategy to stand up to Putin and save lives?
