The shamed son of Pink Floyd guitarist Dave Gilmour was jailed for 16 months today after hurling a bin at a car in the royal convoy during the student riots.
Charlie Gilmour, 21, went on a drink and drug-fuelled rampage during the protest, the court heard.
As he was jailed, Judge Nicholas Price QC said: 'I have to take into account that you have had many advantages which are denied to most young men who come before this court.
'In short, you should have known better than to engage in such a criminal and reprehensible way.'
He added that it 'defied belief' that the 'intelligent' defendant, who went to a £9,000-per-term public school, didn't know the Cenotaph was there to honour the war dead.
The disgraced Cambridge University student also jumped on the bonnet of the car, which was carrying close protection officers, blocking the driver’s view of the Prince’s Rolls-Royce in front, it was claimed during the case at Kingston Crown Court.
Just four weeks ago he had secured a 2:1 at the end of his second year.
Today, his university refused to say whether he would be allowed back to complete the final year of his course.
Gilmour had admitted violent disorder after joining thousands demonstrating in London's Trafalgar Square and Parliament Square last year.

During a day of riots he was seen hanging from a Union flag on the Cenotaph and leaping on to the bonnet of a Jaguar car that formed part of a royal convoy, the court was told.
He was also found to have also hurled a rubbish bin at the vehicle.
The court heard the Cambridge University student had turned to drink and drugs after being rejected by his biological father, the writer Heathcote Williams, and had taken LSD and valium in the hours leading up to the violence.
A 100-strong baying mob laid siege to the royals during the tuition fees protest in London on December 9 last year, the judge heard.
During the five-minute onslaught, the windows next to the Duke and Duchess of Cornwall were smashed and the car battered by rubbish bins, sticks, fists and paint.
Judge Price added: 'I have no doubt you felt strongly about the legislation regarding student fees, but what you did went far, far beyond proper protest.'
He said it would be 'wrong to ignore who the occupants of the three cars were' and that this was an aggravating feature in the case.
Although Gilmour was not sentenced for his behaviour at the Cenotaph, he was told his actions were 'reprehensible'.
'Such outrageous and deeply offensive behaviour gives a very clear indication of how out of control you were that day,' he said.
'For a young man of your high intelligence and background to profession that you did not know what the Cenotaph represents defies belief.
'You showed disrespect to those who made the ultimate sacrifice defending this country.'
Gilmour's barrister, David Spens QC, insisted his client was 'ashamed of himself' for his behaviour, which was sparked by his 'intoxication by drink and drugs'.
The young man had been described as 'out of his mind' by the time he arrived in Parliament Square that day as he had been drinking and taking drugs since the previous night, he said.

This was the culmination of a continual binge that had started around August, 'born out of unhappiness rather than hedonism'.
Giving a frank account of Gilmour's personal problems, Mr Spens told the court this had been precipitated by an 'emotionally painful' meeting that summer with Mr Williams, his natural father.
'In his words, he spent most of the week 'tranquillised out of my mind',' he said.
'This young man has had to cope with the pain and considerable emotional upheaval of having a biological father who rejected him for no good reason and has continued to reject him throughout his life.
'He's been not only absent but entirely disinterested.'
Prosecutor Duncan Penny said yesterday a royal protection officer sitting in the front seat of the Prince’s limousine reacted with shock after under attack. She had dismissed the crowd's mood as merely ‘boisterous'.
Mr Penny said: ‘At first he thought the mood was merely boisterous with the crowd chanting and waving banners and flags.
‘But the inspector said people then started kicking and punching the vehicle, making obscene gestures and striking the car with sticks.

He said how one man stood in front of the vehicle with his arms raised, a person threw a large cardboard box into the carriageway forcing the car to veer and another man raised a large black bin to shoulder height and threw it at them.
‘The window next to the Prince of Wales shattered but remained in place but the window next to the Duchess of Cornwall was broken and almost completely open.
‘He estimates the vehicle was under attack for at least five minutes and was deeply concerned and was under extreme levels of pressure.’
A constable sitting in the Jaguar following the Rolls-Royce pushed his car door open to fend off the attack, striking a number of protesters with the door, including Gilmour.
The yob responded by sitting on the car’s bonnet, causing the driver to brake suddenly. The officer was later injured when a bottle was lobbed through the door, hitting him on the forehead.
The Jaguar was also covered in spit from the jeering crowds who chanted: ‘Off with their heads’, ‘Tory scum’ and ‘Give us some money’.
In a third vehicle carrying members of the Royal household, the back window was smashed.
Prince Charles’ equerry, Major Will Mackinlay was ‘very concerned and fearful for the people in the vehicle and also concerned about how the police protection officers may react,’ the court heard.
Gilmour claims he was so high that he cannot recollect whether he threw a bin at the Royal protection officers’ car.
Minutes later he looted a mannequin’s leg after smashing his way into Topshop with other protesters causing £50,000 with of damage and terrifying customers and staff who needed counselling afterwards.
Dressed in a black suit, white shirt and black tie, Gilmour showed no emotion as he was led down to the cells.
His adoptive father David Gilmour and mother, writer and journalist Polly Samson, had accompanied him to court. They refused to comment after the sentencing.
Gilmour, went to Lancing College, in West Sussex before starting at Cambridge.
