It doesn’t matter. But when you are linking the application with the GCKey account, the particulars being asked, like date of birth etc, should be of the principal applicant.
If you are 2 sponsors and you are sponsoring your parents (2) then for GcKey linkage purposes, number of members should be 4. Please note that GCKey linkage should be done by the principal applicant, not the sponsors
