Foreign Office documents seen by ITV News show that ships importing gas from the Middle East are having “citadels” built into them and barbed wire placed around them due to the threat of piracy.
The revelations come on the day that Ofgem has warned that energy prices will increase due to the extra reliance on imports.
ITV News Business Editor Laura Kuenssberg reports:

The boss of energy regulator Ofgem has warned that the looming shutdown of several coal power plants will raise energy bills further.
