LONDON (Reuters) - British Prime Minister Theresa May won approval from the lower of house of parliament on Monday for a law designed to create an independent customs policy after Brexit.

Lawmakers in the House of Commons voted 318 to 285 in favor of the customs legislation, known as the Taxation (Cross-Border Trade) Bill, which will allow the government to levy duties on goods after leaving the European Union.

The bill must also be passed by the House of Lords to become law.
