Germany's coalition 'walking on the brink of disaster'

A large majority in the German parliament has approved expanded powers for the EU's main bailout fund.

The vote was seen as a test of Chancellor Angela Merkel's authority, as some in her coalition vowed to oppose the bill.

Many Germans are against committing more money to prop up struggling eurozone members such as Greece.

Gero Neugebauer, a political scientist at Berlin Free University, told the BBC's Jon Sopel that despite the vote Angela Merkel's ruling coalition was still "walking on the brink of disaster".
