John King comments:
The Police Reform and Social Responsibility Bill is here, and it's not good news for live music. It will allow Local Authorities to object to TENs.

And it clamps down on TENs being used to bypass licence conditions. This would prevent pubs from u...sing TENs to get round restrictions on the number of musicians allowed to perform.

Looking on the bright side - should the proposed exemption ever surface - most live music would no longer require a TEN.
