This strongly-worded FT editorial is a good antidote for that terrible Guardian one (and I know whose paper's take I trust on most things, generally speaking — and I've contributed to both!):
As the democratically elected president of Egypt – by a thin majority – Mr Morsi is obliged to govern for all Egyptians, not take dictation from the Supreme Guide of the Brotherhood. He should scrap the referendum, and sit down for talks without preconditions with the opposition National Salvation Front, an alliance of some two dozen groups headed by Mohammed ElBaradei, the liberal Nobel laureate.
The temptation will be to press ahead, reliant on the tacit backing of the army, whose enormous privileges the new charter jealously protects. But the imperative need is for a constitution that commands much more consensus, for Egyptians to feel they have a future they do not have to keep fighting for in the streets.
