Democrat presidential contender Senator Bernie Sanders' plans to ask for a "partial recanvass" of the results of last week's Iowa caucuses, after the party released an update showing Pete Buttigieg to be the winner.
A Sanders campaign aide confirmed the plans ahead of a Monday deadline for candidates to ask the Iowa Democratic Party to recanvass the results. A recanvass is not a recount, but a check of the vote count to ensure the results were added correctly.
The state party released updated results showing Pete Buttigieg leading Sanders by two state delegate equivalents out of 2,152 counted.
The Associated Press newsagency believes the results may not be fully accurate and are still subject to potential revision.
Technical issues with a phone app plagued the caucuses and the Iowa Democratic Party failed to release any results to the public until nearly a day after the event. Behind the scenes, party volunteers reported inconsistencies in the complicated maths used to calculate the outcome of each individual caucus.
Iowa Democratic Party officials spent much of the week collecting paper records of the results and checking them against the numbers reported by volunteers.
The state party asked campaigns to submit any evidence of inconsistencies in the final results, and pledged to issue any corrections by Monday.
