Russia could be planning to sabotage a North Sea pipeline from Norway to the UK cutting the country off from a vital supply over the winter months, it is reported.
The 5,500-mile Langeled pipeline takes around a fifth of the natural gas that the UK uses and Western intelligence is believed to be concerned that it could be targeted by Russia.
Parts of mainland Europe have been left without vital gas supplies due to pipelines from Russia having the amount delivered reduced or entirely switched off.
