Membership soared following Friday’s result, according to Labour MP Richard Burgon, which saw Theresa May’s Conservatives fail to win an outright Commons majority.
Labour had been expected to sustain heavy losses but the results vindicated Mr Corbyn’s heavily maligned leadership after the party put in its best performance in years, winning a total of 262 seats.
Google searches for how to join the party surged following the shock result, which saw Labour gain 30 seats. The new membership applications have brought total membership numbers to 800,000. Conservative Party membership figures were just under 150,000 in December 2016.
