Fusilier Lee Rigby was murdered in Woolwich,
south London, in May 2013
A British Muslim has pleaded guilty to posting videos on YouTube glorifying the killing of Fusilier Lee Rigby.
Royal Barnes, 23, of Hackney, east London, recorded and uploaded three videos shortly after the murder in Woolwich, south-east London, last May.
In one of the videos, he hailed the murder as a "brilliant day" and in another he mocked the outpouring of public grief, the Old Bailey heard.
His wife Rebekah Dawson, 22, also uploaded the videos online.
The trial has been adjourned for sentencing reports to be prepared.
In one of the videos posted under his account Musa Real Talks, Barnes laughed uncontrollably as he drove past floral tributes for Fusilier Rigby.
He pleaded guilty to three counts of disseminating a terrorist publication and one of inciting murder.
His wife, who had insisted on wearing a veil in court, had admitted disseminating a terrorist publication at a previous hearing and is awaiting sentence.
Barnes, who associated with one of Fusilier Rigby's murderers Michael Adebowale, also posted on Facebook the offer of a reward for avenging the rape of an Iraqi woman.
The post on June 12, 2013, stated: "Any1 who kills an invading soldier in Muslim land I will give them a Vauxhall Astra 3door and money (French British American any kaffir soldier take ur pick)."
None of his 500 friends replied to the request.
Michael Adebolajo, 29, and Michael Adebowale, 22, will be sentenced later this month after they were found guilty of murdering Fusilier Rigby.
The British Muslim converts ran the soldier down in a car before hacking him to death with a meat cleaver and knives in a frenzied attack.
