' [...] The relentless bombardment of statements from business interests attacking Brexit may have been orchestrated from 10 Downing Street but they were for all that genuine. Major investment banks and transnational corporations, the CBI, the Bank of England, Lloyds, the European Round Table of Industrialists, the International Monetary Fund, the OECD Š these are the go-to institutions if one wants to know where leading sections of capital stand, and they all denounced Brexit.

On the other hand, there may be referendums on the break-up of the United Kingdom, probably in Scotland, conceivably in the north of Ireland. And there is an immediate fight to be waged against the Bourbons of the Labour right. Unity against racism, austerity and war, and to preserve the political opening that Corbyn's election marked is urgently needed.'
