It may still be the season of goodwill, but that has not prevented feisty Amy Macdonald stoking up some Edinburgh-Glasgow rivalry by accusing fellow Scot and X-Factor winner Leon Jackson of "lazyitis".

Leon, 19, was meant to be playing the Hogmanay Concert in The Gardens show in Edinburgh but backed out at the last minute after suffering tonsillitis.

Immediately after her performance at Glasgow's New Year's Eve bash in George Square in front of 15,000 revellers 20-year-old Macdonald called into question Leon, from Livingston's "staying power", insisting tonsillitis was being used an an excuse to mask some birthday excesses.

Macdonald, from Bishopbriggs, said: "Tonsillitis doesn't harm your vocal chords at all. I have got tonsillitis too and I had to phone NHS 24 so I could get some penicillin today.

"I think Leon has got lazyitis, if I am honest. He hasn't even done anything. If he misses one of his first gigs it doesn't say much for his staying power.

"Just wait until he is really into it and is having to go to different countries and trying to become known in other territories. It is going to get much tougher for him than it is just now."

A spokesman for Leon said the teenager was still in bed ill and unaware of the comments.

He added: "I wasn't aware Amy had become a doctor. Leon was honoured to be asked to do Hogmanay in Edinburgh but doctors advised him not to sing. Seeing as he's a singer that poses a problem."

Macdonald was followed on stage by indie band The View, who headlined the Glasgow Hogmanay, which is now badged as part of the Winterfest' celebrations.

Last year the young Dundee band were propping up the line-up, which was due to be headlined by the Fratellis before being called off after George Square was devas-tated by a storm.

The organisers of the event were yesterday still thankful this year's festivities did not succumb to the elements.

Glasgow's Lord Provost, Bob Winter, last night paid tribute to the organisers and party-goers who ensured the event passed without significant incident.

He said: "Glasgow's Winterfest celebrations have been a tremendous success. Hogmanay saw upwards of 15,000 revellers enjoy what is undoubtedly one of the best parties in Scotland if not the world.

"We intend to build on the great success that is Glasgow's Winterfest and hope that revellers will view it as a global destination."
