Can I enter the UK without British Passport

[kankerot]

So have to travel to the USA urgently, UK passport of my son not been returned, can he leave the UK and enter the US on his US passport?

Also what happens on his return to the UK?

I assume his passport will be returned before we intend to come back - will it be best for it to be sent to the USA?

Travel to the US has nothing to do with his UK passport or British citizenship. You can leave the UK with any passport you hold.
He should come back to the UK using his British passport to be admitted as a British citizen rather than a US visitor

Ok, so we are good to go, we can get the UK passport posted to the US and use that to come back to the UK.
