Och här har du en direktlänk gällande Emergency passport:

"The Emergency passport is usually issued the same day but there might be occasions when you need to come back the following day. You do not need to book an appointment but you must come when the passport section is open for Emergency passports which is Monday, Tuesday, Thursday, Friday 9-11. Wednesdays closed."

Hm...
