I'm in the UK, too, and as far as I'm aware, there's no palm-oil free marg to be found.
I made this recipe just yesterday, though... and it's really good! It's super simple, too... so I plan to make it for all my butter needs from now on. It works out super cheap to make, too, if you can get cheap coconut oil from an Asian supermarket.http://www.veganbaking.net/recipes/fats ... gan-butter
The only thing that's not readily available is the lecithin, but I had some anyway, which I originally bought from Amazon.
