The series - due to be written by an Oscar-nominated screenwriter - has been shelved.
In August 2014, Channel 4 announced what it said would be a new "bold and provocative" drama series.

The production firm involved - Mammoth Screen - subsequently had its computers attacked.
The project has not moved forward because of a failure to secure funding, the company says.
