A Metropolitan Police marksman is due to go on trial over the fatal shooting of Chris Kaba.
Martyn Blake, 40, is accused of the murder of 24-year-old Mr Kaba in south London on September 6 2022.
Mr Kaba died after being shot once in the head through the windscreen of an Audi car in Kirstall Gardens, Streatham.
Blake, who in the case was formerly referred to as NX121, has denied the charge against him.
His trial is being heard before Mr Justice Goss at the Old Bailey and is expected to go on for up to three weeks.
A jury is to be sworn in before prosecutor Tom Little KC opens the case against Blake on Wednesday.
