Economic growth in the US slowed at the end of last year, as trade and investment declined and the country was hit by hurricanes and labour strikes.
According to the US Commerce Department, the economy expanded at an annual rate of 2.3?tween October and December, down from 3.1% in the three months before.
The pace, fuelled by solid growth in consumer spending, was nevertheless weaker than economists had forecast.
The figures come amid heightened uncertainty about the path for the world's largest economy, as US President Donald Trump calls for a policy shake-up.
