And isn't David Davis ex-'them' territorials? Not sure if that carries with it the same kudos, but I think he's spot-on.
DD was briefly in 23 - passed selection, but then got moved/promoted in his civvy job and packed it in. Julian Brazier (Canterbury) is ex-21, but is a bit of a kn*b in my personal experience. Andrew Robathan was quite rude about DD banging on about his one year as a weekend wonder, having done two tours with the regt.
Still not bad that there are four with a Them connection in the House.
