We are just back from a few days in Italy. We landed in Manchester on the 23rd of May. Was told to go through e gate so I did. When we got through the line, I realized there wasn’t anyone to look at my brp so I asked about it at the desk on the way out. She got one of the passport control officers who took me around to his station, scanned my brp and checked my fingerprints. He thanked me for stopping and asking and said I shouldn’t use the e gate and should always make sure my brp gets scanned.
On another weird note, we couldn’t get either of my thumbprints to match, though my index fingers matched immediately.
