New Year revellers brave the cold

Partygoers started arriving early to get prime spots along the River Thames

Millions of revellers around the UK are braving freezing temperatures to welcome in the new year.

In London, crowds started lining the banks of the River Thames hours in advance of the fireworks display.

They were played a series of video messages, from the likes of London Mayor Boris Johnson, actress Dame Helen Mirren and Homer Simpson.

Some 100,000 party-goers in Edinburgh will need more than good cheer to keep warm with lows of minus 2C.

A range of New Year events are also underway in Cardiff, Manchester and Birmingham.

Thermos picnic

About 400,000 people are expected to attend London's fireworks, while Elton John is playing at the O2 Arena.

Supt Brian Pearce, of the Metropolitan Police, said the revellers appeared to have heeded warnings to arrive early to get a good view of the show.

He said: "The viewing areas started to fill up at about six o'clock this evening."

Partygoers waiting for the stroke of midnight were entertained by giant projections and light shows on the walls of the city's landmark buildings.

Many came equipped with wine glasses, thermos flasks and picnics.

The Hudson family, who had travelled from Nottingham for the event, sported flashing bunny ears.

Nurse Corinne Hudson, 47, explained that the family had planned the trip on New Year's Day last year when she was undergoing chemotherapy for ovarian cancer.

She said: "My hair started falling out on New Year's Eve last year. So we spent last year crying.

"Watching it on the television everybody seemed to be having a good time here whilst we just weren't. So that's why we're here tonight to put that behind us and move on."

'Insane Londoners'

The crowd were played a series of video messages, beginning with an address from London Mayor Boris Johnson, in which he urged the city to "go forward with enthusiasm" into 2009.

Actress Helen Mirren told the crowd that despite the fact she was on the other side of the world, her heart was with "insane Londoners".

"And you've got to be insane, because I bet it's freezing," she said.

Veteran actor Michael Caine said he would normally wish for a "prosperous" New Year.

But instead he said: "This year I think what we really need is luck, so good luck everybody."

The party in Edinburgh - the self-styled Hogmanay capital - has been under way for a number of days already, to build up to the bringing in of the new year.

Events will include fireworks around Edinburgh Castle, live bands and a huge singalong of Auld Lang Syne, which organisers hope will break a world record.

In Cardiff revellers will be able to sleep off their partying in an inflatable tent staffed by medics at the Millennium Stadium.

The sleepover centre has been converted from an emergency chemical decontamination tent.

Persistent cold

Sub-zero temperatures were forecast for northern England and Wales, while many other areas could also see the mercury plunge.

BBC weather forecaster Rob McElwee said the coldest weather would be in north-west England and England-Wales border areas, with temperatures dropping as low as minus 7C.

Belfast would see temperatures on New Year's Eve of minus 2C, London around zero, and Cardiff just below zero, he added.

There is unlikely to be any let up in the cold weather for the first days of 2009.

On New Year's Day cold temperatures and lots of fog are set to persist, with thickening fog over north-west England and the West Midlands.

A little sunshine may break through in western Scotland, Wales and southern England. Spots of rain and snow may fall in north-east England and eastern Scotland, with a possibility of black ice.

By 2 January more sunshine is expected, but the cold weather will remain for the foreseeable future.
