I dont have the accuracy but I think the couple who divorces after the filipina (wife) gained her british passport will automatically validates the annulment of marriage if the wedding was held in the philippines.
if they divorced before the filipina gained a british passport, she still have to apply for annulment in the philippines irregardless of the length of time she stayed in UK.
So i find it more convenient for a filipina to get married in UK because it doesnt affect her status in the Philippines if ever the marriage break down before her citizenship.
