A window fitter from Caerphilly has been accused of killing a farmer in a supermarket car park.
Timothy Higgins is on trial at Cardiff Crown Court. The 22-year-old is charged with manslaughter.
He is also charged with causing the death of 48-year-old Christopher Gadd while driving without a licence or insurance.
Higgins denies all the charges.
The incident happened in a Sainsbury's car park in Pontllanfraith on 4th March this year.
Christopher Gadd was in the car park with his brother Paul.
Prosecutor Owen Williams said he would be making a case that the Mr Higgins deliberately swerved his vehicle to the right in order to drive at Christopher Gadd.
He said the defendant attempted to reverse out of his parking space to leave but was unable to, which led to him becoming "annoyed".
The court heard the defendant had a provisional licence at the time.
The defendant said he heard a “thud” and thought Mr Gadd had punched his car, but when he looked in his mirror, he was on the floor.
He denied intentionally hitting Christopher Gadd.
The trail continues.
