The nerve agent that has killed one person and left another seriously ill in hospital was in a perfume bottle, according to the brother of the man fighting for his life.

Matthew Rowley told BBC News that his brother Charlie had picked up a perfume bottle.

Matthew said he has seen his brother and he was still upset with his condition.

And it was "absolutely not the brother I know", he said.

Ewan Hope, the 19-year-old son of Dawn Sturgess, who died after being exposed to a nerve agent first developed by the Soviet Union, has called on US President Donald Trump to discuss his mother with Russian President Vladimir Putin at the leaders' summit in Finland.

Mr Hope told the Sunday Mirror newspaper: "We need to get justice for my Mum."

Ms Sturgess and Mr Rowley fell ill on June 30 in south-western England's Amesbury, a town near the city where Russian former spy Sergei Skripal and his daughter were poisoned with Novichok in March.

Britain has blamed the attack on the Russian Government; Moscow vehemently denies responsibility.

Detectives confirmed on Friday that a small bottle of Novichok was found in Rowley's home and experts were trying to determine if it was from the same batch used on the Skripals.

Ms Sturgess, 44, died after coming in contact with the toxin.

Police would not confirm the brother's claims about the nerve agent being in a perfume bottle.

Late last week police did confirm that a "small bottle" was discovered in the house.

"A small bottle was recovered during searches of Charlie Rowley's house in Amesbury," counter-terrorism police said in a statement.
