England just about rode out a second-half fightback from Argentina as an eye-catching Twickenham debut from Max Ojomoh helped extend their winning streak to 11 successive Tests.
Ojomoh scored one try and made another with a crossfield kick in the first half as England stretched out into a 17-3 lead at the break.
Their advantage could have been even more emphatic had hooker Luke Cowan-Dickie not had a try ruled out for a slight knock-on on the final play of the first half.
Argentina, who fought back from 21 points down to beat Scotland last weekend, crowbarred their way back into the contest though.
Justo Piccardo slid in before a pair of penalties from Tomas Albornoz and Santiago Carreras reduced the deficit to 17-16 on the hour.
But England seemed to recapture the momentum just in time.
A big break from Alex Coles set up a platform from which Ojomoh popped up for Henry Slade to stroll in under the posts.
George Ford’s conversion and penalty pushed England 11 points clear, only for Rodrigo Isgro’s converted try in the final minute to set up a grandstand last play.
The Pumas, needing a try to snatch victory, pounded away, with support from a small but loud collection of fans in the stands.
However, a final line-out, within 10 metres of the England line, went astray to wild cheers from the majority of the 80,807 spectators and Alex Mitchell kicked to the stands to ensure his England side successfully round off a 2025 that has featured only one defeat, a reverse against Dublin in February.
