An exact expression of Lense–Thirring precession rate is derived for non-extremal and extremal Plebański–Demiański spacetimes. This formula is used to find the exact Lense–Thirring precession rate in various axisymmetric spacetimes i.e., Kerr–Newman, Kerr–de Sitter etc. We also show that if the Kerr parameter vanishes in the Plebański–Demiański spacetime, the Lense–Thirring precession does not vanish due to the existence of NUT charge. To derive the Lense–Thirring precession rate in the extremal Plebański–Demiański spacetime, we first derive the general extremal condition for Plebański–Demiański spacetimes. This general result could be applied to obtain the extremal limit in any stationary and axisymmetric spacetimes.
