Coup d'état? what coup? what état?

Unbelievable! Hamas's victory over Fatah in Gaza has been described as a "coup d'état" by Margaret Beckett, the UK's foreign minister. I've found the coverage quite remarkable so far in that I haven't heard one credible, even respectable, commentator blame anyone on the Palestinian side for this. Maybe I haven't been paying attention but I thought the conditions for a coup d'état were a state and an overthrow of its legitimate authority by unelected forces, like say, the army. Or do we have to redefine state now to make the zionists look generous?
