It is sometimes unkindly said that military intelligence is an oxymoron. But while the exposure by Dutch authorities of the identities and activities of four members of Russia’s GRU military intelligence service is embarrassing for the Kremlin, we should not be misled by their apparent ineptness.

The somewhat crude nature of their cyber-hacking efforts – the aerial hidden beneath a coat, the laptop revealing past missions, and taxi receipts showing the group’s movements are not the point.

The most salient element of these revelations is the sheer brazenness of the attempts by the GRU to hack agencies investigating the Salisbury poisoning, the alleged downing of Malaysia Airlines flight MH17 by a Russian missile, and the World Anti-Doping Agency responsible for the banning of Russia from world athletics.

Even before the Netherlands released unprecedented details of its intelligence about the GRU’s activities, this was not “covert” espionage as we would normally recognise it. The Salisbury attack itself was carried out using a weapon which would almost certainly identify Russia. One of the most sinister aspects of the Kremlin’s actions –despite the official denials and the ridicule of the allegations in Russian media – is the extent to which they are happening in plain sight.

What should the response be? Jeremy Hunt, the Foreign Secretary has called for the EU to follow the US in imposing sanctions. An international cyber-defence effort is underway.

But America is also currently carrying out the biggest ever investigation into Russian interference in its electoral process. Labour’s Tom Watson has called for a public inquiry here on similar lines. He is right – it is naive to think our own democracy, and the referenda on Brexit and Scottish Independence were immune from such activities. We need to know more about such Russian interference, its impact. Only a public inquiry can give us the answers
