Independent-run Boston BC has lost its chief executive, two senior staff and its deputy leader.
The council has named Richard Harbord, a former chief executive of both Richmond upon Thames and Hammersmith & Fulham LBCs, to take over as interim chief executive for six months.

Mick Gallagher, left, had been chief executive for four years.
His tenure spanned the period in which the Boston Bypass Independents took control of the council on a platform of pressing for a relief road, even though highways is a Lincolnshire CC responsibility.
He had previously been development director.
He said: “After working for six councils over the last 32 years I have decided to take my career in a new direction using the knowledge and experience I have gained in my time with Boston and elsewhere.”
Assistant directors Bev Smith and Richard Micklewright have left to take posts elsewhere and deputy leader Peter Jordan (Ind) has resigned.
The independents remain narrowly in control but have lost seats through by-elections and defections.
Meanwhile, Boston is understood to be resisting overtures from neighbouring South Holland DC to share their chief executive Terry Huggins.
