If ever there was a moment for change in Lebanon, this must surely be it

Without a radical overhaul the next government could look like the one that resigned

Like a break in a merciless heatwave, the fall of Lebanon's failed government has reduced by a few degrees the political temperature in the country's towns and cities. One week after the enormous explosion that levelled much of Beirut, its rulers have rightly paid a price. The power of the street had exposed the fragility of Lebanese leaders. Impunity hadn't won the day after all.

But what seemed like much needed relief is more likely to be the start of a familiar pattern; the same line up of ministers who quit in disgrace will now take on a caretaker role, while those who really control the country haggle over the next incarnation of a government that is likely to look very similar to the one that has just resigned.
