Did Simon Jupp advise the Transport Secretary on new “Hi Viz” livery?

We know that Simon Jupp, fearing a wipe out at the general election, puts a lot of thought and effort in upping his profile locally. 

So was it our Parliamentary Private Secretary who advised Mark Harper to introduce a new livery for “Team Transport”? 

Please alert Owl to any sightings of Simon sporting his PPS coat (or is it only for ministers?)
