There are four ways the UK can go from here with regard to Brexit, and all of them are bad. Read the first direction: hard Brexit, or no deal.
Second: soft Brexit, the EU’s deal
Hard Brexit will be unthinkable catastrophe for the UK, and cause some damage to each of the EU-27 countries. EU-27 are prepared and ready to offer a deal to the UK, but as EU-27 are better-prepared to negotiate, have better negotiators, and are in a stronger position (they can survive the damage done by no-deal Brexit; it is uncertain whether the UK can or not) the deal for the UK on leaving the EU will be set in terms that will favour the EU.
