More than 100,000 people have applied to register to vote since the start of the week, with young people making up the bulk of the surge against the backdrop of a momentous 48 hours in British politics.
On Monday, 52,408 applications were submitted, according to government figures, followed by 64,485 on Tuesday.
The figure on both days was significantly above the typical number for weekday applications, which has averaged about 27,000 for the past month.
Parties that have traditionally drawn support from younger people will be most encouraged by the figures, which show that 58% of applications submitted on the two days were from people aged 34 and under.
