The campaigning dad of a man found dead in a cement mixer in Upminster took to Parliament Square this week in a high-profile rally against alleged police corruption.

Les Balkwell, from Elm Park, was one of dozens of grieving families at the protest yesterday (Tuesday June 12), who believe their loved ones deaths were covered up by various police forces in the country.

Les’s 33-year-old son Lee Balkwell was crushed in the mechanisms of the industrial lorry in Baldwin’s Farm, Dennises Lane, nearly tens years ago.

He has always maintained his son, a dad-of-one, was murdered and the subsequent investigation botched by Essex Police.

He spearheads a campaign for a full murder probe.

Les told the Recorder: “I believe the day caused ripples and from little across big oak trees grow. It’s another step in my pursuit of justice for my son Lee.”

Les was joined by Alistair Morgan, the brother of murdered private investigator Daniel Morgan, who was killed by an axe-blow to the head. It is thought Daniel had been examining alleged police corruption in the Met and his killers have never been brought to justice.

Also there was Michael Spalding, who believes his daughter Tamzin Spalding was murdered in 2008, but the death was not properly investigated.

The protest coincided with an important meeting into police accountability, held by top officers near the Houses of Parliament.
