The defence secretary Philip Hammond has said he can't go ahead with sweeping cuts to the Armed Forces with also cutting senior positions. He said:
At a time when we are making difficult decisions about defence spending and have had to accept reductions across the board, we cannot ignore the volume of posts at the top.
For too long the MoD has been top-heavy, with too many senior civilians and military.
Not only does this new structure reduce senior staff posts by up to a quarter in the next two years but it allows clear strategic priorities to be set for the Armed Forces.
It will hold the frontline commands to account for their delivery and support them in the tasks they are set.
