meant to add this quote, sorry.
"Dual citizen holders
If you’re a dual citizen with British or Irish citizenship, you cannot apply for an ETA when you travel to the UK. Instead, you’ll need to prove your citizenship using:
A valid British passport.
A valid Irish passport.
Another valid passport containing a certificate of entitlement."
