I strongly welcome the Defence Secretary’s continued leadership on Ukraine. I visited Estonia in early September, just prior to the incident in which three MiG-31 Russian fighter jets entered Estonian airspace and stayed for 12 minutes, in a further dangerous escalation of tensions in the region. Even before that incident, the sense I got from the Estonian politicians I met was that they were very much on the frontline, and there was deep concern that, if Russia succeeds in Ukraine, they will be next. What assurances can the Defence Secretary give that contingency plans are in place to support our NATO allies in the face of continued Russian aggression?
