Other districts that are part of the urban area ( but not part of Merseyside ) are Ellesmere Port and Neston and Halton . The designation `` Greater Merseyside '' has been adopted for the area that includes Merseyside and Halton , the term `` Liverpool City-Region '' is less well-defined . However , a separate ` City region ' , comprising Merseyside and Halton , has some official recognition as being Greater Merseyside , although it has also been referred to as Liverpool City Region .
