The MOD are considering 'scrapping' their tanks in an attempt to modernise the way they fight on the land.

I'm in two minds about this. Yes they can put the fear of god in opponents and can cause a fair bit of destruction, but these days, they are quite vulnerable from missiles fired from the air or the ground (I remember that Saddam's tanks didn't last long).
So perhaps they have had their time and a new approach is required. For example, could small combat drones achieve the same sort of results? It could cost the same, but is somewhat safer for the operators.
