No 10 seeks to tackle Scottish independence threat after loss of two heads of unit tasked with maintaining union
Boris Johnson has set up a cabinet committee to maintain his grip on keeping the UK union together, after two former heads of the No 10 unit devoted to the issue left the post within weeks of one another other.
Oliver Lewis, a key aide who was appointed to head the No 10 union unit, quit last week after just two weeks in the role. His predecessor Luke Graham was let go earlier this month.
