Some 632,863 applications to vote were submitted on Tuesday, the last day to register before the General Election, Government figures show.
The number is just below the 659,666 applications that were submitted on the equivalent deadline day ahead of the 2019 general election.
People had until 11.59pm on June 18 to register to vote.
The number of applications submitted on Tuesday is the highest for a single day so far in 2024 and is nearly double the year’s previous high of 330,621 on June 13.
It means more than 2.7 million applications to vote were submitted from May 23, the first full day after Prime Minister Rishi Sunak called the General Election, to June 18.
