Conservative holdout puts Austria coalition in question after vote

VIENNA (Reuters) - Austria's government formally resigned on Tuesday but will stay on in a caretaker role as wary conservatives consider whether to renew a coalition with the centre-left after they suffered big losses to the far right at weekend elections.

Chancellor Werner Faymann's Social Democrats (SPO) are putting all their efforts into forming another coalition with their People's Party (OVP) junior partners to keep power with the mainstream parties that have dominated post-war politics.
