The march was preceded by a small Critical Mass which took to the streets with messages taped to their backs.
The march could have done with a privatisation specific banner, as the standard chants did not communicate the issues we were protesting about. However there were some good leaflets (which hopefully will be posted here) that would have done a good job of communicating the issues to those who took them and read them.
