Threat to Life

London is a dark city in the middle of the night- these are the words of Iranian journalist Aliasghar who received a threat to life warning from the Met police. The police told him he was in immediate danger in the capital. In Paul Caruana Galizia's last series, Londongrad, he uncovered the extent of Russian money hidden in London. In season two he comes across another foreign power operating in the city and sets off to try to uncover who is behind the threats.
