Dr Julian Lewis: As a matter of superior tactics, does my right hon. Friend accept that the right way to deal with a robotic, sneering psychopath firmly in the grip of small-man syndrome is not to impose sanctions in a piecemeal and gradually escalating way but to seek to inflict maximum economic pain at the earliest possible moment?

[The Secretary of State for Foreign, Commonwealth and Development Affairs (Elizabeth Truss): Yes is the answer, and that is what we are doing; we are pushing as hard as we can for the toughest possible sanctions. This is the biggest package of sanctions the UK has ever put in place in our history, and we want to do even more and we want to push it with our allies. Together with the G7, we represent half the global economy, and that is what will really shift Putin’s behaviour. That is what will really degrade the Russian economy and stop him being able to fund his war machine.]
