An influential lobby group for U.K. businesses will on Friday warn that a crash-out Brexit would shrink the country’s economy by 8% and put thousands of jobs at risk. On Thursday , the ratings agency S&P Global Ratings said it could reassess its guidance on U.K. banks if the country is forced into a disorderly exit from the EU.

Elsewhere, Ford Motor Co. F, -0.57% has launched an overhaul of its European business. It will include thousands of job cuts, plant closures and the cancellation of low-profit models amid poor performance at the global car maker, The Wall Street Journal reports. In the U.K., no decision has been made over whether to close engine and component plants in Dagenham and Bridgend.

Trade talks between China and the U.S. are still progressing, with China’s top trade officials expected to visit the U.S. later this month for more negotiations.
