Sir Julian Lewis: Will my right hon. Friend explain to the House who actually does the research that leads to people being identified for sanctioning, whether there is resistance in such places as the City of London, which no doubt could make enormous financial profits from having illicit money deposited there, and whether such places are incentivised to turn a blind eye when attempts are made to camouflage the real sources of the dirty money flowing in?

[Sir Iain Duncan Smith: Many groups are doing that research at the moment, some of them private and voluntary organisations, but the Foreign Office itself is meant to be doing it. I am struck by the fact that it does not always check everybody’s backgrounds. The reality is that it must be much more intense and we must start going after these people. The City of London had a bad reputation for dirty money. A lot of that has stopped now as a result of the Russian sanctions. More importantly, individual sanctions also helped to end that. We need to be much more particular about where that money is coming from and how, and who are the individuals who are behind the use of that money. My right hon. Friend is quite right about that.]
