It is the biggest victory ever for the team, breaking the previous record of 13-0 against Hungary 16 years ago.
White entered the game with two goals to surpass Kelly Smith’s previous record of 46 goals, which took him just nine minutes. The 32-year-old pulled off her hat trick.
She was one of four hat-trick scorers of the night – Lauren Hemp scored four times, while Beth Mead and substitute Alessia Russo also recorded trebles.
Beth England scored a brace, and there were also goals from Ella Toone, Georgia Stanway, with a penalty, Jess Carter, Jill Scott and Jordan Nobbs in a historic night for the Lionesses, who were leading 8-0 at halftime.
It was the sixth win in six Group D appearances for England, their first six appearances under Sarina Wiegman who saw 43 goals scored and none conceded.
After breaking the scoring record, White said, “I just feel really, really emotional about it. We have been talking about it for a long time and I am very proud of it.
“I’m really proud of the girls tonight, we have so many girls who scored their first goal for England.”
Mead started things off with a third-minute finish, shortly after Alex Greenwood fired a shot against the crossbar.
White then tied Smith’s score in the sixth minute with a magnificent strike just outside the box, before breaking the record three minutes later by scoring from close range with Stanway assisting for both goals.
There was no relaxation for Latvia – 94 places behind England in 102nd in the world – as Mead scored her second of the contest in the 12th minute and Hemp returned home in the 18th for her first goal international. Mead then completed his hat trick with a header five minutes later to make it 6-0.
Some respite for the visitors followed, before a strike from Toone and a hemp header came quickly just before half-time to see Wiegman’s side lead 8-0.
White’s hat-trick was sealed four minutes into the second half when she landed a shot from the edge of the box that goaltender Laura Sinutkina couldn’t prevent from reaching her.
And England hit double digits three minutes later, with Stanway rightly winning on the scoresheet with a penalty following a foul on Mead.
The substitutes started to come in with Carter touching home in the 56th minute, Beth England scored again in the 61st and Scott, also introduced from the bench, then made it 13-0 in the 67th.
This put England tied for the score of their biggest win – and it was quickly eclipsed as Russo, who had replaced White on time, opened his international account with a header to take the team to 14.
The deluge of goals continued with Hemp scoring his third, Nobbs becoming the last substitute to score, Russo scoring twice in two minutes for his hat trick, and Beth England going on to register his second of the game.
The unbelievable rout then ended in the 88th minute as Hemp got his fourth to take the score to 20-0.
