Exiting the European Union (Sanctions)

I am a bit confused about the Government’s attitude. The permanent under-secretary gave one reason why we could not have these sanctions in place already, the Foreign Secretary has given three different versions of why it could not happen and now the Minister has given yet another version of why it could not happen thus far. Part of it seems to be that the Government are not yet ready, which feels a bit like foot dragging to me, because I remember that the Government did not want this amendment in the first place, but the House insisted on it. The Government still seem to be arguing that we cannot do this because we are still a member of the European Union. In fact, Estonia and Lithuania have exactly those provisions, and nobody has thought to strike them down. There are 49 Russians listed in both those countries. Why can we not do it?
