joining me now is sir tony brenton, who was the british ambassador to russia from 2004 to 2008., what do you make of what the foreign secretary has been saying in the united states, calling for intensification of sanctions against russia after salisbury? you can understand why he is so outraged by this whole affair in salisbury and all that. and he obviously, he would ta ke all that. and he obviously, he would take this and they have done more in europe as and they have done more in europe as and we have, the problem with all of this is that simply piling sanctions on russia has been an unproductive policy. i'm making this number up, but ten rounds of sanctions on russia, all they have done has been to reinforce, reinforce putin and his bad behaviour. and to some extent pushed russia out of lanes of the us and strong with china. is that a sensible policy was white the alternative is to do nothing and not punish attacks with nerve agents, we have already taken action with what happened, salisbury, there's already been action. we are intensifying action against dirty russian money
