The US dollar jumped in value against other currencies and shares rose on Thursday after President Donald Trump promised what he called a “phenomenal” tax plan in the next few weeks.

German Chancellor Angela Merkel has warned Britain cannot be given any special treatment after its vote to leave the European Union.

The records appear to show Trump’s businesses lost $916m, (816 million euros) suggesting the loss would have been large enough to wipe out more than $50m (45 million euros) in annual federal taxes over 18 years.

Ireland’s government insisted it has done nothing wrong as the Dublin parliament debated its fight with the European Commission over Apple’s tax bill.
