LONDON, Nov 21 (Reuters) - European stocks opened lower on Tuesday and the euro hit an eight-day low against sterling as a governing crisis in Germany weighed on markets.

On Monday evening German chancellor Angela Merkel said she would prefer fresh elections to ruling with a minority government after talks on forming a three-way coalition collapsed.
German President Frank-Walter Steinmeier said Germany was facing its worst governing crisis in the 68-year history of its post-World War Two democracy and pressed all parties in parliament "to serve our country" and try to form a government. events have already been likened to Germany's Brexit-moment," said Daniel van Schoot, an economist at Rabobank.
