BBC News image copyrightGetty Images As mobile operators step up efforts to roll out 5G networks, they face resistance from local groups convinced that the new technology poses a threat to health. In the city of Bath, in Somerset, one such group is celebrating a victory after the local council refused permission for a 5G mast - with the backing of the local MP. It's a decision which has sparked dismay not just from the mobile industry but from the minister who has been urging councils to smooth the way for the rollout. Digital Minister Matt Warman said that while he could not comment on a particular planning case, "there is no credible scientific basis that 5G has an adverse impact on people's health".
