The pound versus the greenback is testing the highest from October 1 as Boris Johnson said that EU will examine UK proposals objectively. Johnson said to reporters that there is no path to a deal except through replecaing the backstop. Johnson indicated also that he has given a guarantee that the UK will never conduct checks at the Irish border. It is also worth to mention that Johnson has asked in parliament for a vote on the UK proposals. Having backing for the “new deal” and going to the EU summit with that would be more powerful.
