Gilmour will serve 16-month sentence for violent disorder committed during the student protests

Charlie Gilmour, son of Pink Floyd guitarist Dave Gilmour, has lost his appeal against the 16-month prison sentence he was given in July.

Gilmour, who is 21 and was studying at Cambridge University, was jailed in July after being found guilty of charges of violent disorder after he was filmed defacing the Cenotaph, throwing a bin at a car carrying Prince Charles and smashing a window.

Lord Justice Hughes, who was presiding at the Court of Appeal today (October 28), said that he was unable to state that the sentence given to Gilmour was “arguably either manifestly excessive or wrong in principle”, reports the Press Association.

Gilmour had admitted during the original trial that he had taken both LSD and valium before the incident and did not remember throwing the bin. He also claimed that he did not know what the Cenotaph was before he defaced it.

The 21-year old has already served over three months of the 16-month sentence, meaning he will be eligible for parole in early 2012.
