Encouraging signs for Hillary Clinton, as millions of Americans cast their votes early.

Figures from some of the key battleground states show the Democrats improving their share of votes.

They've gone better in North Carolina, Nevada, Arizona and even Utah...compared to the same point in the 2012 campaign.

Utah is the big surprise, as it's a very conservative and Mormon-heavy state.

Polls there show the race between Mrs Clinton and Donald Trump looks very tight.
