The study, titled Autumn surprises: possible scenarios for the next phase of Brexit, details five possible scenarios that could develop in the run up to Britain’s scheduled EU departure date in March 2019. Four of the scenarios conclude with Britain leaving the bloc without a deal. The report’s authors said: “There are five basic scenarios but the key backdrop to all of this is that there are currently two defaults in place, which mean that, if nothing else happens, the UK will exit the EU without a deal on 29 March 2019.” On Thursday, the Government will publish the first in a series of technical notices in preparation of the possibility of a no deal Brexit.

The notices will include advices for businesses, citizens and public bodies. Brexit Secretary, Dominic Raab, has said that agreeing on a deal is the “most likely outcome” and has played down the prospect of leaving the EU without any formal arrangements. Mr Raab said: “Securing a deal is still by far the most likely outcome, but we want to ensure we clearly set out the steps that people, businesses and public services need to take in the unlikely event that we don’t reach one.” Around 70 technical notices are expected to be published by the government between late August and the end of September.

4pm update: A potentially no-deal looming Brexit means that pensioners should invest sooner rather than later according to an expert Moira O’Neill of Interactive Investor, an online trading and investment platform, said: “If you need income, but can delay buying an annuity for a few years – which might be a good idea, as the rates improve as you get older – look at a drawdown arrangement. “Since the pension freedoms were introduced in April 2015, growing numbers of people have opted for drawdown schemes, whereby they can take sums directly out of their pension pot as income, while leaving the rest invested. A no-deal Brexit could give investors a bumpy ride, so those in drawdown should consider not eating into their capital, to allow it to recover.” 2.45pm update: MPs demand more expenses to tackle Brexit fatigue MPs have been demanding for more expenses to recruit staff because Brexit has been adding to their workload.
