US Democrats have made gains in state elections, in what is being seen as a blow to President Donald Trump.

Democrat Andy Beshear claimed victory in Kentucky's governorship vote, after a tight race in the conservative-leaning state.

Meanwhile, democrats seized full control of the legislature in Virginia for the first time in over 20 years.

The results are a gauge of the political mood ahead of next year's presidential election.

Republicans held on to power in the Mississippi governor vote, following a closely-fought race in the traditional Republican stronghold.

US state governors head the executive branch in state governments.

In Kentucky, Mr Beshear claimed victory over incumbent republican governor Matt Bevin after final results gave him a lead of 0.4%.

Mr Bevin, 52, says he will not concede, citing unspecified "irregularities".
