President Donald Trump has vetoed the annual defence policy bill, following through on threats to halt a measure that has broad bipartisan support in Congress and potentially setting up the first override vote of his presidency.

The bill affirms 3% pay raises for US troops and authorises more than 740 billion dollars in military programmes and construction.
