The Serpentine has been shut to swimmers from the swimming club by the Royal Parks due to icy conditions (their words).
"The Royal Parks have informed us that the lake is now closed to swimming due to the icy conditions (my words not theirs'). They are very concerned with regards to the ice and the danger of anyone falling through etc. The gates to the swimming area are now locked at both ends. Please do not try to gain entry as this really would jeopardise the club's current very good relationship with the Royal Parks.
The position will be reviewed on Monday."
Earlier some of the swimmers were on the BBC, (BBC footage)
