Hillary Clinton's former rival for the Democrat presidential nomination will join her at a rally in New Hampshire on Tuesday and is expected to offer her his endorsement.

A statement from the Clinton campaign updated the details of the rally as an "event with Bernie Sanders and Hillary Clinton".

It read: "US Senator Bernie Sanders on Tuesday will join Hillary Clinton for a campaign event at Portsmouth High School to discuss their commitment to building an America that is stronger together and an economy that works for everyone, not just those at the top."

Mr Sanders' left-wing campaign won an unexpectedly high level of support against the early favourite Ms Clinton, and his supporters have been reluctant to give their backing to the former First Lady.

Tuesday's rally takes place in a state where Mr Sanders beat Ms Clinton in a primary in February by 22 points.

And it follows weeks of private negotiations between the Clinton and Sanders campaigns, with the latter hoping to influence Democrat policy towards a more liberal and socialist agenda.

Ms Clinton's previous endorsement events have been hit by repeated cancellations, with rallies alongside Barack Obama and the vice-president Joe Biden postponed over the Orlando and Dallas shootings respectively.
