London's government has released a list of items that may be subject to retaliatory tariffs in response to U.S. President Donald Trump's 10% import tariff decision. The release of the list marks the start of a four-week consultation period with businesses to discuss the potential impact of such tariffs. The list includes products that make up approximately 27% of the UK's imports from the U.S. as of 2024, according to a government document for consultation.
