A four-try haul by Marlie Packer helped England beat Italy 61-33 in the Women's Six Nations to record a 37th consecutive Test victory.
England secured a bonus point inside 14 minutes at Stadio Sergio Lanfranchi but John Mitchell’s world champions were pushed afterwards and only held a 40-19 lead at the break.
Packer added to her first-half brace with two more scores after the interval in a superb individual display to keep England on track for another grand slam ahead of next Sunday’s trip to France.
Injury-hit England were forced into a last-minute change after Maddie Feaunati was ruled out, but they needed only four minutes to break the deadlock when Packer touched down Zoe Harrison's kick.
Amy Cokayne grabbed the first of a double five minutes later before Helena Rowland spotted a gap and raced over.
When Mia Venner grabbed a fourth try for the visitors in the 14th minute to put England 26-0 up, Italy looked set for a long afternoon, but they responded with aplomb.
Vittoria Vecchini got Italy on the board three minutes later before a penalty try for the hosts was followed by a Alissa Ranuccini score.
Packer had grabbed her second by this point and Abi Burton got England off the mark after half-time.
It was followed by two more Packer tries, with Harrison able to add the extras in a 16-point haul, but Italy replacement Francesca Sgorbini went over in the 56th minute before she grabbed another on the stroke of full-time to help the hosts win the final quarter.
Later, France ran in 11 tries to overpower Scotland 69-28 in Edinburgh and set up a Grand Slam decider against the Red Roses.
Les Bleues had gone ahead inside the opening minute at the Hive Stadium when Manae Feleu went over in the right corner before Scotland – showing seven changes from the defeat by Italy – responded with a driving try from Rachel Phillips on her first start. France captain Feleu was then shown a yellow card following the 16th-minute try.
Despite being a player down, France swiftly restored their lead when Carla Arbez collected her own kick to run in and then also made the conversion. Siobhan Soqeta and Lea Champon both went over in the space of three minutes to secure France’s bonus point before Phillips dived in for another Scotland try. A second try from Champon, though, saw France have a 31-14 lead at half-time.
France took the game away from Scotland with a relentless second half. Pauline Barrat burst clear just two minutes after the restart, with Soqeta getting her second just before the hour off a lineout. Another try followed for Alexandra Chambon from a driving maul and then winger Lea Murie ran through a fine solo effort in the 63rd minute.
Scotland regrouped as Emily Coubrough went over to reduce the deficit with 12 minutes left only for France to respond again as Annaelle Deshayes barged across from close range. Aicha Sutcliffe crashed over for a debut try with a minute left to get Scotland a bonus point, but France had the final say with a close-range score from Ambre Mwayembe ahead of the buzzer.
