(b) This had nothing to do with Mansion House, it just so happens that Mansion House is right by Bank underground station.

2. Some important news was expected to break today, as indeed it did. The Bank of England announced a ¼ percentage point rise in UK interest rates, taking them to a five-year high of 5%. The photographers were being contained in the area opposite the Bank of England.
