@ljem I didn’t speak to my MP but I did send them a direct message on twitter. Although I didn’t get a response, I had the passport approved 2 days later.
This is what I sent them on 2nd July :
Hello, we have submitted our daughters renewal which has been marked as ‘application being processed’ since 19th June. We are due to travel to Spain to visit family on 23rd July, is it likely her passport would be approved by this date or do I need to look at cancelling our flights and accommodation?

Thank you.
