With 66 MPs quitting, the Conservative party is going to lose a great deal of institutional memory, amounting to over a millennium of cumulative parliamentary experience. With the political environment shifting, the Tories face a challenge from this departure, which may eclipse the extraordinary turnover of 1997.
Notable MPs leaving the party include Bill Cash, who has served since 1984, and an unexpected number who resigned after serving just one term. This trend of resignations is also evident in Labour, where a wealth of experience is being left behind by long-serving members like Margaret Beckett and Harriet Harman.

Experts speculate that this enormous exodus is being driven by expectations of sustained opposition and a yearning for new viewpoints. However, in order to prevent stagnation and adjust to changing circumstances, parties must learn from previous setbacks and seek advice from individuals who have lost seats.
The departure of experienced members of parliament highlights the necessity of strategic analysis and adjustment in response to changing political circumstances, particularly as the Conservative party prepares for a possibly stormy era of rejuvenation.
