My son (minor child) will be visiting the UK for a short (one week) school trip in October. His British passport expired 2 years ago and I have not renewed it since he rarely visits the UK (last visit was 2019), can he enter the UK with a EU country passport (he has double citizenship) or is UK Border control going to cause problems on entry if they discover that he is a British Citizen? Should he take his expired British Passport with him?
Thank you
I tried to look for answers online and I only found this on Reddit:

I even contacted FCDO, but apart from suggesting to request a new passport they referred me to UK Visas and Immigration which can only be contacted by paying money
