The National Portrait Gallery (NPG) has been accused of nepotism after it hosted a photography exhibition by a large donor to its £40m makeover.

Zoë Law’s work is on display until 2 March in the Studio Gallery and Spotlight Space, with the organisation also acquiring her portrait of Noel Gallagher for its permanent collection.
