Zimbabwe fails to reach agreement

Zimbabwe\'s ruling party and opposition have reportedly failed to reach a power-sharing agreement at a summit of Southern African leaders in Johannesburg.



South African President Thabo Mbeki, who is mediating in the crisis, said talks would continue.



The Movement for Democratic Change (MDC) is insisting that President Robert Mugabe surrender his executive powers.



MDC leader Morgan Tsvangirai is said to have agreed in principle to take on a powerful prime ministerial role in a new national unity government, although the exact balance of power is undecided.



Mr. Mugabe has still not conceded.
