And now Spain's Marca reports that Jerez is being touted as a new option, so that winter testing can remain in Europe but avoid the problems of Barcelona and the costs of Bahrain.
When asked about the Bahrain proposal, Williams' Paddy Lowe said: "As far as I know, it's not going to happen for now.
"I think it was clear during the course of last week that there is not enough support to do it.
"I think Barcelona is on the table and Jerez is an option and there may be other places to consider as well, but those are the two most likely," Lowe added.
