LONDON  --  Britons snowed in by the wintry weather have been flocking to an extra-marital dating site in the last 24 hours.

IllicitEncounters.com, which provides a platform for married people to conduct affairs, said on Wednesday it has seen an unexpected increase in visitors over the past 24 hours, and received a record number of new profiles on Wednesday morning.

The website said most new members are registering from areas worst hit by this week's extreme weather, including Hampshire, Berkshire, and the West Country, and the site has taken on several temporary staff members to cope with the rush.

"In light of these figures, I'd be interested to see how much work those 'working from home' have actually done," IlicitEncounters.com spokeswoman Sara Hartley said in a statement.

"Perhaps these wives and husbands have just been waiting for a time when they could join, away from the eyes of their work colleagues and, most importantly, their partners..."

The website said it has gained 2,567 new members in the last six days, suggesting that January will be its busiest month ever.

It says it has more than 350,000 members in Britain and that its aim is to create a safe and non-judgemental environment where married men and women can meet each other.
