Slightly worrying:

Tony Blair may be preparing to abandon Britain’s veto over law and order policy in Europe on the eve of his departure from Downing Street this month, MPs fear.

What might this mean?

If the veto goes, Britain could be outvoted on a range of criminal law
matters, including hot pursuit powers for cross-border police
activities, courts procedures and data sharing.

Courts procedures? Why, might that mean trial by jury? Could it mean the use of questioning after charge? Our continental partners do not have the former and do have the latter, so both would be likely targets of "harmonization" as and when that occurs.

Well, not to worry, eh? Our own government is moving to change those laws anyway.
