Did you hear the bang!?

Many of you are asking what the "big bang" was on the Commons on Wednesday morning.

As a large open space very close to the centre of London, we occasionally get a call from the local police when they need to carry out a controlled explosion, as was the case on Wednesday.  It is usually at quite short notice so we don't get an opportunity to warn visitors on the Commons that it is happening.

We understand it was a substance that was regularly used in school chemistry labs that the Government has now deemed to be unsafe to store and what was blow up on Wednesday was an amount of that from London schools.

If you missed it, here's a video of the event - with apologies for the poor quality.
