expiring UK passport

[tezzaaa]

My wife has dual nationality: Thai and British. She is currently in Thailand. Can she travel back to the UK if her UK passport only has 3 months left? And would she be able to return to Thailand if her UK passport only has one month left?

She would be checking in with her Thai passport so I guess it should be fine but I thought I'd double check..

If she's going back to UK of course, no problem.  But while there why wouldn't she renew her passport?  In any case yes she could of course return on her Thai passport but it would seem a good idea for her to get a new UK one whilst she is there to avoid issues on her next UK visit.
