British Foreign Secretary David Lammy stated that the U.K. aims to increase defense spending to 2.5 percent of GDP by 2027.

U.S. Secretary of State Marco Rubio said on Thursday that all NATO members will have agreed on a goal of spending the equivalent to 5% of GDP on defense over the next decade by the 2025 NATO Summit in June.

Slovenia and several NATO member states are seeking ways to expand the definition of defense spending as they attempt to meet US calls to allocate more funds on security, the nation’s prime minister said.
