Germany braces for ‘nightmare’ of Russia turning off gas for good

Ministers fear flow may never restart as annual maintenance work soon begins on Nord Stream 1 pipeline

Germany is bracing itself for a potentially permanent halt to the flow of Russian gas from Monday when maintenance work begins on the Nord Stream 1 pipeline that brings the fuel to Europe's largest economy via the Baltic Sea.

The work on the 759-mile (1,220km) pipeline is an annual event and requires the gas taps to be closed for 10 to 14 days. But never before in the pipeline's decade-long history has Germany seriously been asking whether the flow will begin again.
