The British government ramped up actions to help protect businesses and households from some of the economic tumult created by President Trump’s decision to raise tariffs and upend the norms of global trade. The government said on Sunday it would suspend tariffs on 89 products for about two years to help businesses and consumers save money. The products include those for construction, such as plywood and plastics, and everyday household items, such as pasta and fruit juices. Officials will also increase financing support for exporters by 20 billion pounds ($26 billion), through partial loan guarantees, and give small businesses access to loans of up to £2 million. Officials have said they want to move quickly to support companies as they try to sustain fragile economic momentum.
