Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many times Russian military (a) aircraft and (b) ships have entered British territory in the last 12 months; what the average response time was for the armed forces on each of those occasions; and what the type and model was of the aircraft or ship on each of those occasions.

I can confirm that there have been no unauthorised incursions by Russian military aircraft into UK sovereign airspace in the last twelve months.

There have been three authorised Treaty inspection flights by Russian military An-30b aircraft in UK airspace under the auspices of the multi-national Open Skies Treaty. On each occasion the UK received advance notice of the aircraft's arrival and it was hosted for the duration of its mission at RAF Brize Norton.

For information on Russian naval assets entering UK territorial waters I refer the hon. Member to the answer given on 24 March 2015 by the previous Minister of State for the Armed Forces (Mark Francois) to Question number 218391.
