LONDON (Reuters) - Britain’s opposition Labour Party said on Thursday it would respond in full to the announcement of a post-Brexit trade deal with the European Union, but that it had long argued a deal was in the national interest. “Since the election, the Labour Party has urged the government and the EU to secure a trade deal because that is in the national interest,” a Labour spokesman said in a statement. “We will be setting out our formal response to the deal in due course.” Labour leader Keir Starmer is expected to hold a news conference later on Thursday.
