The Metropolitan Police are close to agreeing compensation with the family of Ian Tomlinson, who died after being pushed to the ground by a riot officer during the G20 protests of April 2009.
The Deputy Mayor for Policing and Crime in London, Stephen Greenhalgh, has authorised the Met to settle the claim.
It is thought an announcement could be made within the next few days.
Mr Tomlinson’s widow, Julia, and seven of his children and step-children have pursued the compensation claim
Mr Tomlinson had been walking home when he was struck with a baton and pushed to the ground by PC Simon Harwood during protests in the City of London.
The 47-year-old newspaper seller collapsed minutes later and died of internal bleeding, in what was later found by an inquest jury to be an unlawful killing.
