It was obvious before the election that when the new government came into power, they would have to grasp the nettle and pass some legislation that would be unpopular - it wasn't a coincidence that the previous one had avoided doing a thorough weeding.
I am sure most of us have started to tame a neglected garden. How long did it take? First you have to find out just what tangle of vegetation you are dealing with, then you have to decide what to save, what to eliminate, and what to prune back or train into a new shape. Only then can you plan new flowerbeds, order plants, plant seeds and bulbs and so on. Will it all be thriving and ready to enjoy after a few weeks?
How long do you have before the gardening season is over for the year and you must pause and gather strength for the next bout?
How can you politely tell your highly critical neighbours that when you bought the house you also bought a spade, a fork, a strimmer and a pruning knife, not a magic wand that transformed the garden overnight into an earthly Paradise?
There have been only a few weeks for the incoming government to survey the prospect before them (with different eyes and more accurate facts and figures) and to start making solid plans and taking preliminary action, before Parliament closed down for the recess. Also, remember, both parties have had a hectic time fighting an election, and the Labour party has had to choose and brief the team which will do the bulk of the horticultural work.
That action cannot take place immediately, because there have to be discussions and votes before any legal rules are altered - there may be changes at this stage. Then the practical arrangements have to be put in place.
As Monica says, it will be at least a year before any effect is visible of a different approach. There is no magic wand that will change anything overnight
