Alain, it was mentioned briefly on the news covered by both the BBC and ITN. As far as I am aware, there is no real tensions between our two countries. This happens on a fairly regular basis due to the proximity of Russia and the European mainland. As for the Royal Navy accompanying or in reality shadowing Russian naval ships, it is because The English Channel is a very narrow strip of sea and is heavily used by all nations as it is a short cut to the Mediterranean and vice versa. My gripe is that the French Navy appears to sit back and let the UK do all the shadowing (I have not seen any reports of French activity).
The British media is concentrating on three main issues at the moment: Brexit, the NHS and the Trump's administration with the odd forays into North Korea and the Middle East.
