Britain will have to tackle Russian aggression for years to come, said the MI5 chief on Wednesday, adding that his agency had blocked more than 100 attempts by the Kremlin to insert suspected spies into the UK since the Salisbury poisonings.

Ken McCallum, giving an annual threat update, said state-based threats were increasing and said the UK also faced a heightened direct threat from Iran, which had threatened to kidnap or even kill" 10 people based in Britain in the past year.
