Tickets for several Ed Sheeran tour dates went on sale last week - including two nights at Dublin's 3Arena in April - and as you might expect of one of the most popular musicians on the planet, thousands of fans were left disappointed.

However, that disappointment turned to anger at the realisation that tickets were soon appearing on re-sale sites at huge mark-ups.

Sheeran has come out and denounced the practice of re-selling tickets, saying that he had partnered with a UK site called Twickets, which allows fans to re-sell their tickets at face value - similar to Irish site Toutless.

In a press release to PA, he said: "We are vehemently opposed to the unethical practices that occur in the secondary market. We have written to each of our partners, be they promoters, venues or ticketing companies detailing the way in which we expect tickets to be sold: direct to fans. We have also partnered with a company called Twickets, which is a site aimed at the ethical resale of tickets. It allows fans to swap tickets at face value or less; we are pushing them as the official resale partner and a safe place for fans to swap tickets.

"We are aware and deeply concerned about the websites in question and have urged all fans not to engage with them in order to avoid being ripped off with higher prices or, potentially, counterfeit tickets. Once again, we urge all fans to only purchase tickets through official vendors.”

Sheeran kicks off his UK and Irish tour with dates at Dublin's 3Arena on April 12th and 13th - and will be performing at the BRITS ahead of it.
