Egypt vice-president resigns on final day of referendum
Egypt's vice-president has announced his resignation, on the day the country completes its voting in a controversial referendum on a draft constitution.
In the nation's latest political upheaval, Mahmoud Mekki, appointed in August, said he had realised the role did not suit his background as a judge.
Egyptians are voting in the second leg of the referendum, which is widely expected to approve the draft.
However, opponents say this will not end the country's unrest.
