Dame Judith called on the mayor to route violent marches "away from retail areas" and to ask organisers to "provide a bond or other insurance to pay for damage and clean up costs".
Praising police officers for "coping with the aggression", Mr Johnson (London Mayor) said: "I think it's very disappointing that a legitimate march that had the support of hundreds of thousands of people was really spoilt by the actions of a tiny minority."
He added: "Obviously there has been damage to property and it would be a wonderful thing, frankly, if the organisers of the march would contribute to the costs of clearing it up."
We have advocated that those arrested should cover the cost of the policing or an alternative could be to be to pay for the damage that they caused for it could be prooved beyond all reasonable doubt that when they rose first thing that saturday morning their intention was to cause damage.
