This is the first Red Nose Day to take place since the introduction of the Serious Organised Crime and Police Act 2005.
It is now illegal for you to wear a red nose or promote Red Nose Day in any way within the designated area surrounding Parliament if you do not first seek permission from the Metropolitan Police Commissioner.
Wearing a Red Nose (or an aids ribbon for that matter) is a political act; it is an act of supporting a political campaign. Some would call it a political protest. Which, under a badly written law, is illegal within a zone of London around Parliament.
Now, I don’t expect this to be enforced, because it’s a campaign that the government quite like. So it’ll be one rule for those who agree with government, and one for those who disagree, regardless of what the law says.
Which is nice.
