A scotland Yard officer was due to appear in court today accused of killing Ian Tomlinson at the G20 protests.
Mr Tomlinson, a homeless 47-year-old newspaper seller, collapsed and died on the fringes of the demonstrations in central London on 1 April 2009.
PC Simon Harwood, who has two children and lives in Carshalton, Surrey, is to appear at City of Westminster magistrates' court charged with manslaughter.
The Director of Public Prosecutions charged PC Harwood over the death after reviewing an inquest jury's unlawful killing verdict.
Keir Starmer QC said new medical evidence at the inquest and the opinions of experts during the hearing had helped to change his mind.
