British and EU officials say they are deadlocked after four days of negotiations on Britain’s exit from Europe, known as Brexit. The two sides appear to disagree on which parts of Brexit should be negotiated first. EU officials say British negotiators are not clear about what they want. But, the British side says negotiating a trade deal should come before talks on terms for leaving the EU. Another point of disagreement is the amount of money Britain will have to pay the EU when it leaves. Some estimates place the amount at $89 billion. The EU is seeking the money for budget payments and to pay for projects and loans that were agreed to in 2013. That is before the referendum on June 23 of 2016 when Britons voted to leave the EU.
