The spokesman said he would guide reporters away from media speculation that the negotiations were about to enter the final so-called 'tunnel' phase.

Asked if the final talks were close, the spokesman said: "I would guide away from that sort of speculation at the moment. Again, emphasising there are still gaps in our position that need to be resolved to address these problems.

"What we are doing currently is having scoping discussions about potential solutions for these problems."
