LONDON (Reuters) - Goldman Sachs said on Thursday that there could be drama at the EU summit over Brexit but that a thin Brexit trade deal was likely to struck by early November. “Neither the UK Prime Minister’s 15 October deadline nor the European Commission’s 31 October deadline constitutes a hard stop on Brexit negotiations,” Goldman analyst Sven Jari Stehn said in a note to clients. “This week’s European Council may well feature an additional dose of political drama.” “We think the perceived probability of ‘no deal’ will persist through the course of October. But our core view remains that a ‘thin’ zero-tariff/zero-quota trade agreement will likely be struck by early November,” Goldman said.
