Zimbabwe ? President Robert Mugabe and his main rival agreed to divide control of the police and army and strike a delicate balance in Zimbabwe’s Cabinet – but their power-sharing deal will be under enormous pressure from long-simmering differences and economic collapse.

Some members of opposition leader Morgan Tsvangirai’s party were already complaining Friday that the compromise didn’t do enough to sideline Mugabe.

But David Coltart, an opposition member of parliament, said the agreement gives Mugabe “greatly reduced powers to those he enjoys today” and while Tsvangirai will not get “absolute power, he does have substantial power.”

Western nations poised to send in sorely needed aid and investment also are wary of the man accused of holding onto power through violence and fraud and ruining the economy of what had been southern Africa’s breadbasket.
