Four teenage boys have pleaded not guilty to the murder of schoolboy Damilola Taylor.
The boys - one aged 14 and the others aged 16 - also denied assault with intent to rob and manslaughter.
A jury will be sworn in on Tuesday and the trial is expected to last three months.
Ten-year-old Damilola was stabbed to death near his home in south London in November 2000 as he was coming home from an after-school computer class.
He'd arrived in England from Nigeria just four months before.
Because of their age, the teenagers accused of the killing are too young to be named.
They will be allowed to sit beside their parents or guardians instead of appearing in the dock.
