Exclusive: White powder residue found after events held at Chevening and Downing Street, say sources

Traces of a suspected class A drug were found at a government grace-and-favour home after parties attended by political allies of Liz Truss, the Guardian has been told.

The white powder was discovered at the Chevening estate last summer in the days before Truss won the Tory leadership contest and became prime minister, according to sources.
