Shamed Eric Joyce apologised to constituents after his latest court appearance saw him fined £1500.
Moments earlier he had admitted committing a breach of the peace charge when he verbally abused Edinburgh Airport staff and racially abused a police officer following an incident on May 19 last year.
Speaking outside Edinburgh Sheriff Court last Friday, the Falkirk MP apologised to those involved in the incident.
He said he would reflect on whether to continue as the MP for Falkirk, adding: “My instinct is to stay but I don’t know how I will feel in the next few days.
“I am very embarrassed and sorry that it happened. My constituents have seen this before so they might think other apologies are not meant, but they are.”
The former Army major said he had addressed his alcohol issues.
Earlier the court heard that the MP verbally abused an airport worker who was trying to help after he disembarked from a Heathrow flight to discover he had left his mobile phone on the plane.
He then struggled with two police officers who had been alerted.
Defence solicitor Euan Gosney said his client had drank bottles of lager on the flight and wine at the London airport. He added the MP was struggling to come to terms with the death of his brother at the time of the offence.
Passing sentence, Sheriff Frank Crowe said: “This was a prolonged, threatening drink-fuelled rant.”
As well as the fine, the MP was ordered to pay £100 compensation to the airport worker and £50 to a police officer.
Two years ago, he was fined £3000 and banned from pubs for three months after assaulting four fellow politicians in the House of Commons bar.
He later resigned from the Labour party.
Eric Joyce failed to return calls from The Falkirk Herald.
