We've heard from an inside source that Angela Merkel the German Chancellor called Prime Minister David Cameron last night in a bid to block a critical law to make cleaner European cars. Ministers were supposed to agree the law today.
If true, Cameron would be going against what the majority of the public want - cleaner cars - and also turning the existing UK position upside down at the last minute.
On Twitter? Ask Cameron what's going on and if the rumours true. Has he sold out on the UK position?
This is happening right now, all the pressure we can muster will make a huge difference.
