Police are believed to have identified the suspects behind a Novichok attack on a former Russian spy and his daughter in Salisbury.

It's thought a number of people were involved in the attempted murder of Sergei and Yulia Skripal - and have been traced through CCTV and records of arrivals in the UK.

The news comes as an inquest opened into the death of Dawn Sturgess who died earlier this month - after being poisoned by the same nerve agent in Amesbury. Robert Murphy reports.
