A British court has ruled that England cannot leave the European Union without first getting Parliament's approval.
The decision has derailed plans by Prime Minister Theresa May to invoke Article 50, the formal mechanism for England to leave the EU, by the end of March.
The UK government said it would challenge Thursday's court decision.
In a June referendum, 52 percent of British voters voted to exit the EU. The result shocked both the UK and the world.
