CELTIC supporters' joyous celebrations spilled into Sunday as the party to mark the club's first league win in a decade showed no signs of abating.

On the streets of Glasgow, and in pockets all over the country, feverishly happy fans crowded into pubs and clubs, sang and danced outside, and turned the early summer sunshine into a riot of green and white.

The Celtic team and officials were mobbed by eager fans at Glasgow airport yesterday before flying to Portugal for a short break and a friendly match against Sporting Lisbon. Meanwhile, speculation continued over the future of head coach Wim Jansen.

With thousands on the city's streets over Saturday night and on Sunday, police said the revelling was good natured and reported only a handful of arrests for minor incidents, mainly involving drink.

The celebrations were marred, however, by the death of a Celtic fan in a fire in a Maryhill guest house just hours after watching his team clinch the league.

There was also controversy when Irish Prime Minister Bertie Ahern, the first taoiseach to watch Celtic play at their home ground, was apparently refused permission to meet the players after their 2-0 win over St Johnstone.

Mr Ahern, who was at the game as a guest of former Celtic director Brian Dempsey, was said to have been ''very disappointed'' and ''embarrassed'' by the snub.

Two police officers were slightly hurt in Londonderry when a 150-strong mob went on the rampage after a night of celebrations on Saturday.

Police were pelted with stones and other missiles by the crowd, said an RUC spokesman. One person was arrested.

Earlier on Saturday, an estimated 20,000 fans emptied out of pubs in the East End of Glasgow as the premier league season drew to a close. They danced and chanted outside Celtic Park as most of the 51,000 supporters who watched the game went onto the pitch after the league trophy was presented and the players had left.

The partying began in earnest when Harald Brattback scored Celtic's second goal 15 minutes from the end, sealing victory in the championship for the first time since 1988 and ending rivals Rangers' dream of winning 10 league titles in a row.

The roar was echoed at Tannadice - where Rangers beat Dundee United 2-1 - as United fans heard over their radios that the league trophy was heading for Celtic Park.
