Steve,
First, you hate the EU so this sudden alliance you seem to have found is a very temporary marriage of convenience. Second, you are a Tory and therefore disapprove of liberals.

My EU views and politics are irrelevant to this.
Stop trying to make it personal again.

It's crystal clear that there is no evidence implicating Russia that isn't already in the public domain,

Of course there is. Nothing has been released from the police or security services investigations, or technical information from the scientists.

You choose to believe Putin over EU governments.
What in his background makes that a sensible choice?
