“Two heterosexual Irish men marry to avoid inheritance tax on property” (Guardian) neatly combines two recent media sensations: same-sex marriage and whether there should be taxes following death.
[Separately, though of course any marriage is a beautiful event it is unclear why this one was necessary. If you inherit a house that you live in, you may be exempt from taxes under Irish law (source). But perhaps one has to be a blood relation?]
There are probably also a lot of bogus same-sex marriages for the purpose of immigration fraud.
