EU sour grapes? - NOT amateur radio

Although I voted to remain a member, I detect a note of "sour grapes" on the part of the EU. Do I detect a note of bitterness that the UK will no longer pay some of the budget?

It seems perfectly reasonable to me that the UK wants the same policy to apply to all people who wish to live and work in the UK irrespective of the nation they come from.

It also seems quite reasonable that we would want to start work on trade deals whilst we are in the transition period.

No, I am beginning to detect an air of "sour grapes" on the part of the EU. In the end I think the EU will regret this.

All we really wanted was more control over who lives and works here on this small island. We will still trade with EU nations and others as we choose.
