London's mayor Sadiq Khan said on Friday he had asked the organization that deals with militant attacks and disasters in the British capital to assess the impact of a "no-deal" Brexit on access to medicines and food and on law and order.
Khan said he would consult the London Resilience Forum, which plans responses to disasters such as the Grenfell Tower Fire, about the implications for Britain of crashing out of the European Union without a deal, saying that such a "catastrophic" outcome looked more likely than ever.
Britain is due to leave the EU in March 2019, and with time running out to secure agreement on future ties, both British and European politicians are warning of the increased chances of a "no-deal" Brexit.
