The British government's estimate of how much it will have to pay the European Union as part of its so-called divorce settlement is at least £10 billion ($13 billion) too low, a committee of lawmakers said on Wednesday.
Negotiators in London and Brussels have agreed on a divorce bill of £35 billion to £39 billion, due to be paid over the next few decades after Britain leaves the bloc.
The bill was one of the most inflammatory elements of Britain's withdrawal negotiations, with vocal Brexit campaigners in Prime Minister Theresa May's party angry at having to pay anything at all. The agreement was seen as an achievement for May because it came in lower than some had initially feared.
