This did not stop Ms Bright and another protester Lisa Prager giving their presentations as councillors and officials milled about the council chamber.
Later, veteran protester Dick Cuthbert interrupted the meeting to hold up a chastity belt he had made for the mayor.
The belt featured a yellow padlock with the word `wife' on one side and `rates' on the other, to symbolise the personal and public effect of Mr Brown's affair and his failure to declare free hotel rooms and upgrades, which earned him censure by councillors at the last council meeting on December 19.
