"More than two million people have applied to register to vote in the month since Theresa May announced plans for a snap general election on 8 June.
The highest number of applications so far was on 18 April, the day the prime minister made her announcement, when just over 150,000 people applied.
The number of young people registering is the highest of any age group.
The deadline to register online through the official website is 23.59 GMT on Monday 22 May.
The latest official figures published in March, before the election was called, showed that 45.7 million people were registered to vote in a general election as of 1 December 2016.
The Electoral Commission have warned that approximately seven million people across Britain who are eligible to vote are not registered, including 30% of under 34s while only 28% of home movers in the past year have registered."
