An expert in 'radicalisation' was today giving evidence to the public inquiry into the 2017 Manchester Arena terrorist bombing.
This week, evidence covering the 'background and radicalisation' of Salman Abedi will start to be heard as part of chapter 13 of the inquiry.
Abedi detonated a device in a backpack at 10.31pm on May 22, 2017, as concert-goers were leaving an Ariana Grande gig at the venue.
The attack claimed 22 lives and injured hundreds more people.
On Tuesday, the inquiry was hearing from radicalisation expert Dr Matthew Wilkinson.
Dr Wilkinson, an expert in Islamist extremism, has been instructed by the inquiry to compile reports surrounding the issue.
On Monday, the inquiry's chairman ruled against a convicted terrorist and friend of Abedi who had applied to revoke an order requiring him to give evidence before the inquiry.
Sir John Saunders, in his ruling, said Abdalraouf Abdallah was important witness.
"An expert on Islamist extremism I have instructed, Dr Matthew Wilkinson, has suggested that Mr Abdallah exposed Salman Abedi to Islamist extremist views and played a role in radicalising him," said Sir John.

"This is a view I intend to test in evidence with the expert."
