David Cameron may want a politics-free Glasgow Games but campaigners have railed against sponsors’ links to death and human rights abuses at home and abroad.

The Tory PM told business leaders on a jaunt to Glasgow University yesterday that he wanted to steer clear of politics as the clock wound down to last night’s Commonwealth Games opening ceremony.

A crowd of protesters thronged outside the university library where he spoke, with picketers ranging from the Radical Independence Coalition to Our People’s NHS.
