The shocking thing was the Huawei decision, not its disclosure
SIR – There should be a criminal inquiry not into the leak about Huawei (report, April 26), but into the criminal decision on its involvement in building the 5G network. Frank Jones
Cheltenham, Gloucestershire
SIR – We are led to believe that, despite deep reservations among the majority of members of the National Security Council at the prospect of awarding a sensitive contract to the Chinese (which might compromise our sovereignty), the Prime Minister, whose judgment is now recognised as being flawed, still wanted to proceed.
Such a revelation must mean that, on this occasion, whoever leaked the story should be applauded not vilified. David Jones
Cranleigh, Surrey
SIR – The leaker should not be hunted down, but given a medal for risking their career, ironically in the interests of national security. It was a bad decision by our PM apparently to overrule key ministers and threaten relations with our intelligence allies. Neil Kerr
Hereford
SIR – At the start of the First World War it was discovered that many of the materials and the machinery needed for war production came from… Germany.
Little has been learnt in the past 100 years by people charged with strategic planning. We are constantly told that Britain leads the world in technology of this sort. Why is it necessary to enlist the help of a possible enemy? Nicholas Wightwick
Rossett, Denbighshire
SIR – In the latter half of the
20th century, Britain did lead the world in high-technology electronics with companies such as Plessey, Marconi and GEC. What on earth happened to them and the highly skilled workforces they employed and nurtured? Lionel Anderson
Castellon, Spain SIR – The Cabinet Secretary and national security adviser, Sir Mark Sedwill, is said to be so “furious” about leaks from the recent National Security Council meeting that he has launched an inquiry to try to find the culprit.
Perhaps while he is at it he should set up a similar inquiry into the much more widespread and systematic leaks of his own luridly alarmist “confidential” advice to the Cabinet recently, warning of the apparently existential threat to Britain posed by a no-deal Brexit. Nigel Henson
Farningham, Kent
SIR – You report that Sir Mark Sedwill is being urged to hand over the investigation to the police. I wish him luck with that one. If my experience, when my pick-up was stolen, is anything to go by, all he will get is a crime number and an offer of counselling. Justin Smith
Salisbury, Wiltshire
