Labour mayoral hopeful David Lammy has called for an inquiry into how some party members had not received their ballot papers in time to take part in the vote for the new Labour leader.
Lammy, who claimed as many as one in five people hadn't been able to vote, warned there would be a "clamour of people" who would be "very, very upset" that they had been unable to vote before polls closed today.
He told BBC Radio 4's World At One: "One in five people were saying in London that they had not received a ballot and that was up to last night.
"So, I suspect now that this is closed there will be a clamour of people very, very upset that despite being a member or indeed someone who signed up and paid their £3 and hasn't been excluded because they do not share the values of the Labour party, for a few of those people they have not been able to vote.
"Now, the extent of this across the country needs proper inquiry and proper understanding and whether it has affected the ultimate vote, I do not know."
