Tony Wild MLC has pleaded guilty to drinking and driving.
He appeared in court this morning.
Wild, 57, of Fairy Cottage, Lonan, will be sentenced on February 16.
He was more than three times over the drink drive limit when he was arrested by police in Laxey on December 12.
A breath test recorded 108 micrograms of alcohol per 100 millilitres - the legal limit is 35.
Wild, a political member of the Department of Health and Social Care, was reported by a witness who was driving behind him and saw him driving erratically in Laxey.
He stopped his car on Church Hill and went into the Co-op.
As he left the Co-op he was approached by a police officer, who said he could smell alcohol. Wild had to hold a signpost to steady himself, the court heard.
But at police headquarters, he was taken ill and had to be taken to hospital.
Wild gave police a prepared statement, saying: ‘For the avoidance of any doubt I can confirm I drove my car to the Co-op in Laxey before I was arrested.’
His case was adjourned for sentencing, pending probation and psychiatric reports.
Deputy High Bailiff Jayne Hughes granted bail in the sum of £500 with the condition that Mr Wild does not drive, or leave the island without permission.
