The Scot won by nine shots when the tournament was last held at Barseback two years ago and carved out a four-shot lead at one stage on the final day this time around before bogeys at the last two holes gave him a few anxious moments.

Defending champion Westwood got within a shot of the man he replaced as European number one with a birdie on the 16th, missed a good chance to draw level on the 17th and could only par the last when a birdie would have forced a play-off.

Poulter then rolled in his only birdie of the day from 20 feet on the 18th to claim a share of second alongside his playing partner, with five players a shot further back on 12 under including Kent’s Warren Bennett, continuing his good form seven days after he lost out in a play-off to Bernhard Langer in the Dutch Open.

‘‘I didn’t think 70 would be good enough,’’ conceded Montgomerie, who felt at the start of the week that his cup place was not secure after Bernhard Langer’s victory in the Dutch Open had pushed him down to eighth in the standings with only the top 10 guaranteed a spot in the European team.

‘‘I would have thought it would only be good enough for third or fourth but it was more difficult out there than we thought.

‘‘I made a mess of 17 and 18 and relaxed too early but that was okay, I was far enough ahead and it worked out okay.

‘‘I’m delighted to win again having had to beat Lee Westwood’s score by two shots at the start of the day because he’s back playing well again.

‘‘That’s me safe for the Ryder Cup which is nice and it’s a good result for Sam, as last week’s win by Bernhard was. It’s also great for Lee to be playing as well and it’s taking shape.

‘‘Now I can focus on the USPGA championship and concentrate on trying to do well there. I’ll certainly go there full of confidence.’’

Montgomerie’s win, 10 years after his first Scandinavian Masters title, was his second of the season following his Irish Open triumph five weeks ago and his 26th career European Tour title.

It also took him to sixth in the cup standings while Westwood moved up to fourth and Poulter climbed from 20th to 12th.

Westwood and Poulter could both only manage closing rounds of level-par 72 but Westwood in particular was not overly disappointed, having at least shown he had emerged from a worrying slump that saw him miss four of the last six cuts.

‘‘I’m quite pleased even though I missed some short putts, from two feet for par on the ninth and three feet for birdie on the 12th, and you can’t afford to do that,’’ the 28-year-old said.

‘‘I didn’t get too lucky with a couple of lies, when I hit it off line I was severely penalised, but I only made four bogeys all week which is better than it has been.

‘‘It was very good of Monty to bogey the last two holes to give me the chance. It wasn’t to be but at least I gave myself a chance.’’

Westwood will now have a week off ahead of the USPGA Championship having played 12 of the last 13 events.

Poulter will play in the Wales Open starting on Thursday as he bids for more Ryder Cup points before making his debut in the last major of the year in Atlanta having asked for, and received, an invite.

‘‘I didn’t give myself enough chances and didn’t really take any that I did have,’’ said the 25-year-old, who won the Italian Open on his way to becoming Rookie of the Year last season and added the Moroccan Open title earlier this year.

‘‘It was unfortunate to make a bogey on the 14th but good to finish the way I did because I knew I had to make it.’’
