Passport help

Posting here for traffic...(sorry!)

My child's passport runs out tomorrow. We fly on Tuesday.

I have a passport office appt at 8:30am tomorrow. But the information suggests that they won't do children's passports in a day (they do do adult ones in a day). Does anyone know if I have any chance of them doing this?

I'm thinking I could try and get a flight today if that won't happen and then go to the British embassy whilst abroad to get a passport to fly home with.

Any advise/experience welcomed.

As an EU citizen is prove your nationality and identity so Schnoo is technically right. But a passport or national ID card is the only thing that definitively does that. BF officers can run a series of checks with other ID to allow you back into the UK but no guarantees.
The main problem is that airlines get fined for bringing in people without correct documents so just won't allow you to travel.
The Calais-Dover ferry is possible because BF are in Calais and check people before they board the ship

I doubt if any country is going to add us to the visa list because of Brexit.

We didn't need visas to go to many European countries before the UK joined the EU. Passports on their own were good enugh for France, Switzerland, Germany, Belgium, Luxemburg, in my own experience.
