HL Deb 31 March 1988 vol 495 c905WA
Lord Kennet

asked Her Majesty's Government:

Whether, in the light of recent events in the Black Sea, they will ensure that the question of that breadth of territorial sea for NATO member states navies to recognise when operating within the NATO area is discussed, and whether they will seek agreement that the internationally agreed figure of 12 nautical miles is recognised and observed.

Lord Glenarthur

It is for individual NATO member states to decide on the limit of territorial sea they recognise. There is in fact no internationally agreed figure, only a maximum of 12 miles.
