Yesterday was another momentous day in the UK parliament, in which the government was forced to reveal the full legal advice it had received on the Prime Minister’s Brexit deal.

The documents showed the PM was told an arrangement designed to prevent a hard Irish border could last “indefinitely” and the UK could not “lawfully exit” without EU agreement.

With the PM looking closer than ever to losing the ‘meaningful vote’ in the House of Commons on Tuesday- many options seem possible.

One less likely outcome appears to be the prospect of a no-deal scenario, which in turn raises the prospect of a second referendum, but also that the government may fall and there could be a general election.

With talk of a growing rump seeking a watered-down Brexit plan to take back to the EU, we’re still faced with the question of whether the EU may be at all flexible having supposedly set its position in stone.

Where does all this leave business? One newspaper report said yesterday that the government has started writing to 145,000 British companies telling them they need to start preparing urgently for a no-deal Brexit.

But as one leading told Financial Director this week-how can you plan for so many scenarios?
