The full list, which was published on Friday, stated that Sir Keir returned an advance payment of £18,450 to publisher HarperCollins because he was “no longer writing the book for which the advance was received”.
In May 2022, it was revealed Sir Keir was writing a book on his vision for Britain.
At the time, publishing director Arabella Pike said: “In his book Keir Starmer will go back to his early life to trace the origins of his politics and the influences that have shaped him as a leader.
“It will make a fierce argument for the vital role of respect and integrity in political life as he sets out his vision for Britain’s future. We are delighted and excited to be publishing.”
Other registered interests showed that Sir Keir was gifted accommodation for four people in the Gower Peninsula in August last year, which cost £4,500.
Sir Keir also received four tickets to see the National Theatre production of Nye, which focused on the end of former health secretary Aneurin Bevan’s life.
