Boris has other things on his mind

An interesting snippet from Rosa Prince who reports that Boris Johnson

was summoned to appear before the Commons Home Affairs Committee today, but failed to show.
The Committee is trying to get to the bottom of the Damian Green affair and while MPs didn't get particularly far with Jacqui and David Normington last week, they clearly hoped they would have better luck with the Mayor.

and says that its chair Keith Vaz is disappointed

with the response from the Mayor given his public expression of concern at the time of the arrest.

Here here but maybe he had other matters to attend to
