Many thanks for this.
I was a bit worried about this because I dont think the Immigration Rules are very clear on this point. Whilst the unmarries partner visa applies to both heterosexual and same sex relationships I was thinking that maybe the applicants have to show the following to show that their prior relationship has permanently broken down :-
1. If the previous relationship was heterosexual (i.e. marriage) then show it has been divorced or annulled.
or 2. If it was a same sex relationship then show there has been separation.
Therefore different criteria for different types of relationship. Now I realise what I'm suggesting probably goes against the spirit of the Rules (i.e. all types of relationships treated the same) but the trouble is there seem to be very few cases of unmarried partner visas for us to be sure how the rules are applied.
A bit complicated I know but anyone got any further thoughts on this.
Many thanks
