MI5 spy chief Ken McCallum delivered his annual speech on Tuesday outlining his view of the threats to Britain, from hostile states such as Iran and Russia to the development of artificial intelligence.

Iran is stepping up attempts to hit ​harder targets such as military sites in Britain and Russia is increasing its hybrid warfare against Ukraine's allies, the UK's domestic spy ‌chief said on Tuesday.

British Prime Minister Andy Burnham said on Monday ​that a suspected plot targeting the RAF Fairford air base in Britain was "highly likely" to have been coordinated in Iran, and almost ‌certainly directed by the Islamic Revolutionary Guard Corps.

British police on Thursday said that search warrants they secured to search properties linked ‌to Andrew Mountbatten-Windsor had been issued unlawfully and must be quashed, but said the investigation into King Charles' younger brother was ongoing.

British counter-terrorism police investigating a suspected plot involving an air base used by the US said on Saturday ​they had released on bail a dual UK-Iranian national ‌who had been arrested on suspicion of preparing terrorist acts.

Two Iranian nationals appeared in a London court on Saturday charged with plotting ​acts of terrorism involving the use of a homemade bomb to attack the Jewish community in northern ‌England at the behest of a figure believed to be based in Iran.

Britain's MI5 spy agency issued an unprecedented alert on ​Wednesday to warn that a Chinese organisation was involved in funding academic research into topics such as AI on behalf ‌of Beijing's state security service.

Britain's King Charles took the unusual step on Wednesday of responding to criticism by the brother of his late first ​wife Diana, saying via a spokesperson that grief could impact ‌reason, judgment and memory.

The ​British government's refusal to confirm whether it has issued an order to bypass encryption to access customer data ‌held by Apple has become farcical, a lawyer for civil rights groups told a London tribunal on Thursday.

Britain's King Charles will host the leaders of major artificial intelligence companies this week to discuss whether a shared set of principles is needed ​to guide a technology that has sparked growing warnings about its threat ‌to humanity.

The children of Britain's Prince Harry and his wife Meghan are to swap schools after just two days because of concerns over the security of transporting them, ​the couple's spokesperson said on Monday.
