The inquiry into the murder of former Russian spy Alexander Litvinenko resumed on Friday, while this week key witnesses are expected to give crucial evidence to the investigation.
Mr Litvinenko fled to the UK in 2000 claiming persecution and was granted asylum. He died in November 2006 from radiation poisoning - it’s believed this was put in his tea during a meeting with former associates.
