LONDON (Reuters) - More than 50 British lawmakers, 20 of them women and most of them Conservatives, have announced their retirement from politics and not stand for general elections on June 12.

The women MPs attributed this to the fact that they were subjected to bullying and blackmail as a result of the frantic debate over Brexit, which has been going on for three years, as they described.

"The growing mistreatment I have suffered, my staff and my family as a result of the Brexit controversy, has been an important factor in my decision to quit politics, because you are at a stage where you have to protect your home, your family and your loved ones," said Conservative MP Caroline Spielman.

British women MPs began to take their threats seriously, especially after a far-right murder of Labor MP Joe Cox, who was promoting staying in the EU ahead of the 2016 Brexit referendum.
