Jesus Francisco Morales-Agustine (Morales) appeals the 80-month sentence imposed following his guilty-plea conviction of illegal reentry into the United States after being deported.

Morales contends that his sentence is illegal under United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), because it was imposed pursuant to a mandatory application of the United States Sentencing Guidelines. He thus alleges a “Fanfan” error. See United States v. Walters, 418 F.3d 461, 463 (5th Cir. 2005). Fanfan error is not a structural error. Id. However, the Government concedes that the Fanfan error was preserved, so we review for harmless error. See id. at 464. The Government has failed to carry its burden of showing beyond a reasonable doubt that the district court’s Fanfan error had no effect Morales’s sentence. See id. We therefore vacate the sentence and remand for resentencing in accordance with Booker. See id.

Morales contends that the sentence-increasing provisions of 8 U.S.C. § 1326(b) are unconstitutional and that this court should remand his case for resentencing to no more than two years in prison under 8 U.S.C. § 1326(a). As he concedes, this contention is foreclosed by Almendarez-Torres v. United States, 523 U.S. 224, 235, 118 S.Ct. 1219, 140 L.Ed.2d 350 (1998).

CONVICTION AFFIRMED; SENTENCE VACATED; REMANDED FOR RESENTENCING.
