LONDON (Reuters – British republicans declared Monday they will start a campaign for the end of the monarchy as part of celebrations marking Queen Elizabeth’s 70th anniversary on the throne.

Elizabeth, 95 years old, is the oldest and longest-reigning monarch in the world. Buckingham Palace announced plans Monday for celebrations of her Platinum Jubilee, which will take place in June.

Republic, an anti-monarchy organization, used this occasion to announce it would launch a campaign called “Not Another 70”, to demand the end of the historical institution.

A minority of people will celebrate Queen Elizabeth’s 70-year reign. However, everyone must look forward. “The prospect of King Charles does not make for a happy situation, but there are good alternatives,” Republic’s Graham (NYSE) Smith stated.

It’s time for a serious discussion about our Constitution, to accept Charles as not being the best that the country can offer and to recognize that we, the nation, are capable of selecting our heads of state.

According to polls, the majority of British citizens support the monarchy. The queen is extremely popular. However, support is less for Charles her oldest son and heir and there are growing republican feelings among younger Britons.
