This week I have seen two examples of this:
Earlier this week I tracked a post from a governmental source that said 'We continue to believe that no deal for Britain is better than a bad deal. But we want a deal. We want a deep and special partnership with the European Union, and we want the EU to succeed'. (https://www.theguardian.com/politics/2017/may/03/theresa-may-accuses-eu-of-meddling-in-uk-general-election)
I don't see any consistency in either of these messages.
The phrase 'have your cake and eat it' springs to mind
