Unhappy Union Sir: John Power is correct about George Abaraonye, the president-elect of the Oxford Union (‘Violent opposition’, 20 September). Abaraonye appears to advocate that most extreme form of censorship: the bullet. As such, he poses an existential threat to the Oxford Union, which for 250 years has been a beacon of free speech for the world. Invited speakers are dropping out. Donors to the much-needed building repairs appeal are snapping shut their chequebooks. Freshmen with a belief in free speech and open debate will not join. If Abaraonye cared about the institution, he would resign. Evidently, he cares not one jot. He seems to want its destruction. For this reason,

The shale illusion Sir: Your leading article rightly makes the case for extracting as much of our North Sea resources as we can (‘All at sea’, 6 September). However the enthusiasm for developing shale gas is misplaced. As energy minister, I commissioned work to establish how much of the onshore gas in-place could be recovered. The truth is just a small proportion – maybe 10 per cent. An energy policy based on shale would put our energy security at risk. Economically, at a time when global gas prices are expected to fall, UK shale would simply not be competitive and projects would fail. It is no accident that none of

At the end of last month, a fire at an electrical substation in Maida Vale caused chaos in west London. Homes lost power. Transport services ground to a halt. It came in the same week as outages across Spain and Portugal and just a few weeks after a fire at another substation caused Heathrow airport to shut down. We also know that the British government is drawing up contingency plans for Russian attacks on energy infrastructure. All of this raises an important question: how resilient would the British state be in the face of a determined effort to cripple its power grid? The blunt answer is: not very. David Betz,

If the new Trump era has a theme, it’s one of quixotic disruption with random consequences. In that spirit, stand by for more interventions from activist shareholders seeking to electrify sluggish businesses while making fast bucks on the way through. The first episode over here was the attack by the New York investor Boaz Weinstein on seven London-listed investment trusts, in which he acquired stakes and forced shareholder votes to replace board members, with the aim of taking the trusts’ assets under the management of his own firm, Saba Capital. ‘Go home! You’re selfish and wasteful,’ shouted one headline after Weinstein was emphatically defeated in all seven polls. But his

Volt-face Luton’s Vauxhall plant is to close, partly because of the zero emission vehicle (ZEV) mandate which obliges manufacturers to sell increasing proportions of electric vehicles. Remarkably, the history of the electric car can be traced back half a century earlier than the combustion engine. There are several possible claims as to who built the first road-going electric-powered vehicle, but one is a Scottish inventor, Robert Davidson, who produced one in the 1830s, about the same time as Thomas Davenport in Vermont. By the end of the 19th century electric cars were competing with petrol cars, but died out for the reasons the industry is struggling today: it was hard
