Philadelphia: Hillary Clinton will on Thursday promise Americans her ‘primary mission’ in the White House would be to lift up those left behind by an uneven economy, as she becomes the first woman to accept the Democratic nomination.

Laying out the organising principle for her administration, Clinton will tell delegates gathered in Philadelphia that she hopes to be a president that can repair lives hollowed out by global economic change.

‘My primary mission as president will be to create more opportunity and more good jobs with rising wages right here in the United States,’ she will say, according to prepared remarks released by her campaign.

‘From my first day in office to my last.’

Clinton will make a direct pitch to the same working class and poor voters that her populist Republican rival Donald Trump has vowed to champion and who have felt the brunt of globalisation.

She will promise special focus ‘on places that for too long have been left out and left behind -- from our inner cities to our small towns, Indian Country to Coal Country, from the industrial Midwest to the Mississippi Delta to the Rio Grande Valley.’

The already divisive 2016 election, she will say, is a ‘moment of reckoning.’

‘Powerful forces are threatening to pull us apart. Bonds of trust and respect are fraying,’ she is to say.

‘It truly is up to us. We have to decide whether we’re going to work together so we can all rise together.’
