In 2015, Lundgren was one of the nominees for the Parliament Magazine award as the best EU parliamentarian in the transport section.[8][9] This was the very first nominee from the EFDD group. Lundgren did not win the award but said he was happy to be nominated.[10]
In March 2018, Lundgren was accused of groping a female colleague at a Sweden Democrats party event in Stockholm. In 2019, ahead of the 2019 European Parliament election in Sweden, Kristina Winberg, an MEP for the same party, was dropped from the party's ballot and later forced to leave the party on grounds of having "conspired to smear party colleagues with the help of the media" after Lundgren was confronted by an Expressen journalist over the allegations.[12] Lundgren remained a candidate and was re-elected.[13] In November 2021, the Göta Court of Appeal convicted him for the sexual assault, finding that it was "beyond a reasonable doubt" that he had "touched the breasts of the plaintiff against her will."[14] He was sentenced to pay a 60-day fine.[15]
In March 2022, the Swedish Supreme Court announced that it would not grant leave to appeal to Lundgren for him to work as an MEP. In response, it was announced that Lundgren would no longer represent the Sweden Democrats in Brussels over the conviction but would continue to sit in the European Parliament as an independent while keeping his party membership. Lundgren also stated he would contest the verdict at the European Court of Justice, arguing that he had been wrongly convicted.[16]
