After Reading Crown Court found that Matthew Wootten was almost three times intoxicated when his car collided into the entrance to Chequers in Buckinghamshire in June, he was sentenced to prison.
On June 25, just before the general election, when Rishi Sunak was prime minister, he broke through the 80-year-old oak gates.
According to the court, Wootten also struck bollards behind the gate, gravely hurting himself. Over £38,000 worth of damage was caused.
Thames Valley Police reported that the driver, who was the sole occupant of the vehicle, had “suffered serious injuries” at the time.
The Crown Prosecution found multiple alcohol cans in Wootten’s vehicle.
A blood alcohol level of 221 milligrams of alcohol per 100 milliliters of blood was recorded following his arrest. Eighty milligrams is the legal maximum.
Wootten, a resident of Great Kimble, Buckinghamshire, entered a guilty plea to counts of careless driving, driving under the influence, and destroying property when life was in risk.
On Wednesday, he received a sentence of two years and eight months in prison and a 40-month driving ban.
Chequers, which features hundreds of acres of gardens and an indoor pool, has been the official country residence of British prime ministers since 1921.
