For any metal, the reducing property depends upon 3 things: ionisation energy, hydration energy and sublimation energy.

Since hydration energy is highest (even greater than the sum of other 2 energies) for Li among alkali metal, it is the most reducing metal in the solution phase.

The order is as follows: Li > Cs > Rb > K > Na.

Li is the exception in the series.
