The brother of the man who killed 22 people in the Manchester Arena terror attack is due to enter pleas on murder charges later.
The 22-year-old is expected at the Old Bailey this morning, after an initial hearing earlier this month was adjourned.
On May 22 2017, Salman Abedi, 22, detonated a suicide vest at the end of an Ariana Grande concert, killing 22 people and injuring 260 others.
Hashem Abedi, who was raised in Manchester, had already travelled to Libya before the attack.
The defendant, now aged 22, was arrested in Tripoli and was extradited to the UK in July.
It is claimed he made successful and unsuccessful attempts to buy bomb-making chemicals.
He is also accused of helping in the purchase of a Nissan Micra to store device components and made detonator tubes for use in the explosive.
At the time Hashem Abedi arrived back in the UK the Home Secretary Sajid Javid tweeted: "Hashem Abedi has now landed on UK soil. His successful extradition from Libya is an important step forward in the investigation into his brother's evil terror attack at Manchester Arena.
"I pay tribute to all those who have worked tirelessly on this case. My thoughts remain with the victims and their families who have endured so much. Wherever they are, whoever they are, I will alwys do all I can to bring suspected terrorists to justice."
Theresa May, in her final major speech as prime minister, said: "This is clearly an important moment in the investigation. I hope it is a welcome step for the loved ones of all the victims."
