Sterling back on roller-coaster against euro on Brexit reports                                           

Sterling is the most erratic among the Group-of-10 nations after Norway’s krone.

The pound fell to $1.2906, and it was down 0.3% against the euro to just over 91 pence.

Traders are bracing for more erratic behaviour from the pound after it whipsawed on conflicting news about trade negotiations between the UK and EU.

It first fell on reports that officials were at loggerheads on the issue of state aid, and that the EU was starting legal proceedings against the UK over its plans to breach the terms of its withdrawal agreement.
