Moseley

In a statement, the Birmingham Hall Green and Moseley MP said: "I am confident that I have been compliant with Ipsa rules and will fully cooperate with the investigation."

The woolly king rat, sat on top of a mound of knitted black bin bags and holding a crown and cheese sceptre, has been placed on top of a postbox at the Alcester Road and Chantry Road junction in Moseley.

The topper, which also features a knitted wheelie bin and pizza boxes, was created by members of the Moseley Knit and Natter Group.

Martin Mullaney, a community activist and former councillor in Moseley, described the knitwork as the "coronation of the rat king".

"Bristol has got Banksy, eat your heart out, we've got our mystery Moseley knitters," he added.
