By coincidence, the day before the news broke I was in a group visiting the House of Lords. Our "sponsor" was MRAF Lord Craig of Radley, CDS in Gulf War 1. He remarked that he had been honoured to receive a peerage on his retirement and said that most of the ex-Service chiefs in the Lords sat on the cross-benches, from where they could contribute to debates from an informed but non-partisan position.
Exactly as it should be!
