I was very unhappy with Pickles and that Act in 2015.
IIRC it arose because a council in Wales had a Christian act of worship in the council chamber at the beginning of every meeting, and many councillors weren't Christian.
One side argued that those who didn't wish to take part could just wait outside the council chamber until those in the chamber were ready to start council business.
The other side argued that those who wished to worship before the meeting could do so outside the council chamber and at a time of their choosing before the scheduled council meeting.
I think the latter was the right course, and that space should have been available in the building for the small groups having their own acts of worship before the meeting.
Pickles went the other way.
If they're going to insist on spending council time, in the council chamber, on something like this, then a contemplative "thought for the day thing" from a variety of religions and secularists is the way to go. It might actually add something positive; rather than being simply be an exercise in control.
We're no longer in the C15th where a single church controls everything that happens in the country and nigh 100% of the population is Christian. We are actually allowed to be atheist now, or even – horrors! – religions other than Christianity.
