Sir Keir Starmer published details of his taxable income and gains last week, following the disclosure by the Prime Minister, Rishi Sunak of his tax returns. Sir Keir's income and gains are straightforward and we ran them through our software to reconcile back to an exact breakdown of his tax bill. 

Sir Keir has not published copies of his actual tax returns, just a summary, and notes. We have added our commentary as follows
