There seems to be no rhyme or reason for the way passports are being done. We sent to the Glasgow office. Here is the timeline of my mums new passport so far:
Applied online: 18th June
Documents sent: 19th June
Documents acknowledged: 24th June
Application approved: 25th June.
Just waiting for it to be printed and sent now then will update. We are due to go away on 5th August so was quite nervous.
Definitely think people who have been waiting weeks should get in touch with their MP if twitter hasn’t helped.
