British pound stumbles as EU's Tusk criticizes Boris Johnson

The British pound weakened to the lowest level of Wednesday after the president of the European Council, Donald Tusk, tweeted that U.K. Prime Minister Boris Johnson was trying to win a blame game over Brexit. "What's at stake is not winning some stupid blame game. At stake is the future of Europe and the UK as well as the security and interests of our people. You don't want a deal, you don't want an extension, you don't want to revoke, quo vadis?" he tweeted. The pound traded at $1.2213, versus $1.2290 on Tuesday.
