Tickets to Bernie Sanders first public appearance in Ireland have sold out in under five minutes.

The politician is due to visit as part of the Dalkey Book Festival, with his itinerary including a stop-off at the Bord Gáis Energy Theatre for a conversation about his best-selling book Our Revolution with David McWilliams on June 4th.

Tickets - priced from €15 - went on sale at 9am, but subsequently sold out - much to the dismay of many Sanders fans on social media who wanted to 'feel the Bern''.

Somehow Bernie Sanders tickets were "unavailable" at 9.00am on Ticketmaster, yet @cian_roche got his hands on two. #dalkeybookfest pic.twitter.com/8UUhSbYoy0 — Daniel Kelly (@IsMiseDaniel) April 28, 2017

In a tweet following the sale, Dalkey Book Festival said:
