Keir Starmer's brother's cause of death is revealed

A heartbroken Keir Starmer was by his younger brother's side when doctors told his sibling he was terminally ill, it has been revealed.

The grieving Prime Minister has opened up about how his beloved brother, Nick Starmer, was told he had inoperable lung cancer.

Nick, who suffered from learning difficulties, died on Boxing Day, aged 60. Sir Keir, who despite being one of the most powerful men in Britain, is deeply private about his family life and rarely spoke of his sibling's ill health.

He has since paid emotional tribute to his brother, who has described as a 'wonderful man' who had a 'really tough life'.

Now, the PM's biographer, Tom Baldwin, has revealed the true depth's of the Labour leader's tender relationship with Nick, who Sir Keir also supported with cash.
