Miniature statue, what is it for?

Whilst in Manchester yesterday (15th May, 2012) I came across lots of these miniature statues outside the town hall, in Albert Square.

Anyone know what they're for?

Statue miniatures in Manchester

I came across loads of these tiny clay statues on the floor in Albert Square, Manchester today, anyone know what they are, or even for?

They were placed around one of the main statutes in the square, which coincided with the private hire taxis protest at midday.
