One of the most significant factors in the march was its internationalism. African Drop the Debt campaigners protested alongside British Asians from Islamic Relief.
Flags of the Italian party Rifondazione Comunista and the Portuguese Left Bloc were among many from the European socialist organisations.
Despite the police cordoning off many city centre streets, the atmosphere was peaceful. No one could quite work out why the Ann Summers and Body Shop stores on Princes Street had boarded up their windows.
But the peaceful nature of the protest did not mean that it lacked politics. There were few takers for Bob Geldof’s strategy of sucking up to Bush and Blair, and many thousands of marchers took the opportunity to express their opposition to the occupation of Iraq.
