As areas look at models and governance arrangements for joint spatial plans many will be looking at existing models.
Trust me Greater Cambridgeshire, as experience has showed, is a model to not emulate at all costs.
What precisely are its powers? look at its constitution as vague as mud as it fers mostly to existing non statutory informal powers whereas the whole point of a combined authority is to hold budgets and exercise powers.
The following functions are reserved to the Combined Authority Board:
Strategies and Plans
The adoption of, and any amendment to or withdrawal of the following plans
(a) Cambridgeshire & Peterborough 2030 and 4 year plan
(b) Local Industrial Strategy
(c) Local Transport Plan
(d) Bus Strategy;
(e) Skills Strategy;
(f) Housing Strategy;
(g) Investment Strategy;
(h) Delivery Plan;
(i) Non-Statutory Strategic Spatial Plan
(j) Market Town Masterplans for Growth
(k) Rural Strategy
(l) Other strategies and plans as agreed.
Which if any of these are statutory? The MHCLG has for example written three mutually contradictory letters on LTPs, so now we have three separate authorities preparing statutory LTPs.
Compare with the Greater Manchester Combined Authority constitution. Which reads like it has seen a lawyer avoiding an exercise in fudge and where the powers being exercised refer in all cases to statute.
Scrap the amateurish Greater Cambridge combined authority Constitution and start again
