But the agency boss has no plans to exercise his newly-won fight to drive sheep across London Bridge.
The animal was in fact an Oxfam Unwrapped gift sheep that is now set to become a vital asset to a family in the Third World.
It was presented to Jonathan as a memento by his children following the freedom of the City honour.
“For the past few years my children have given me Oxfam Unwrapped goats for birthdays and Christmas but it looks as if it will have to be sheep from now on,” he said.
Jonathan was proposed as a freeman because he is a member of the Company of Stationers and Newspaper Makers – a livery company that dates back to the year 1400.
He is pictured below right, receiving the award from Murray Craig, clerk of the Chamberlain’s Court.
