Michael Adebolajo, 29, and Michael Adebowale, 22, were found guilty in December 2013 of murdering soldier Lee Rigby as he returned to his barracks in Woolwich, south-east London.
The pair drove their car at Fusilier Rigby before attacking him with knives and attempting to decapitate him. The soldier, a father of one from Middleton, Greater Manchester, died of multiple cut and stab wounds after the attack on 22 May. Here is what happened that day.

The men, both Muslim converts, were in possession of a gun and eight knives on the day of the attack. Adebolajo had visited an Argos store in Lewisham, south-east London, the day before the murder to buy a knife sharpener and five-piece knife block set, costing £44.98. The gun, a 90-year-old 9.4mm-calibre Dutch revolver, was not loaded.
Adebolajo handed a letter to witness Amanda Donnelly Martin when she arrived at the scene shortly after Lee Rigby's murder.
Addressed to "my beloved children", it urged people to seek martyrdom, and stated: "If you find yourself curious as to why carnage is reaching your own towns then know its simply retaliation for your oppression in our towns."
