The UK Royal Navy has suspended sat-nav signal jamming during its ongoing Joint Warrior naval exercises following complaints from local fishermen.

The suspension had to be forcibly initiated even after all appropriate actions were taken to warn of the disruption during this year’s exercise.

BBC News has reported Western Isles local authority Comhairle nan Eilean Siar as saying that the jamming had affected internet connectivity, mobile phones and satellite TV, threatening profitability and the safety of fishermen.

Comhairle leader Angus Campbell said: "While the total effect of the jamming is unclear it is totally unacceptable if the MoD’s exercises are causing disruption to island communications networks."

A Royal Navy spokesman said that temporary jamming was common and essential during military exercises that are part of preparation for operations.

According to the military, Joint Warrior is held twice a year and involves Nato warships, aircraft and ground troops.
