LONDON (Reuters) - British Prime Minister Boris Johnson is ready to pull out of Brexit talks unless the European Union agrees to budge on its demands, The Sun newspaper reported on Monday. “Today he will tell the EU he is not for turning as he vows to stand firm against 11th-hour Brexit demands from France,” The Sun said. “But No 10 (his office) said the PM will call time if the EU refuses to budge from their ‘outrageous’ demands.”
