After years leading some of London's most high-profile boroughs, Max Caller has taken on a new challenge with an electoral role. Mr Caller has been appointed an electoral commissioner and will chair the Boundary Committee for England. He said: ‘Having been involved in electoral administration for many years, I am very excited at the prospect of working with the Electoral Commission and chairing the Boundary Committee for England. ‘The committee has developed a reputation for fairness and professionalism and I aim to build on this in the future.' The commission is an independent body established by Parliament to ensure integrity and public confidence in the democratic process. The Boundary Committee for England is responsible for defining local authority and ward boundaries and conducting reviews of local government areas. Father-of-four Mr Caller has already had considerable experience at the electoral coalface, serving as chief executive and returning officer at the three London boroughs of Barnet, Hackney and Haringey. The 57-year-old took on the top job at Hackney after it was advertised as ‘the worst job in local government'. He and Hackney mayor, Jules Pipe, are both credited with turning the authority around when it had reached an all-time low. However, he took early retirement from the post after suffering from heart problems. He came out of retirement to temporarily lead Haringey LBC. Electoral Commission chairman, Sam Younger, said: ‘We are delighted to welcome Max Caller to the team. ‘He has a great deal of relevant experience that will greatly benefit the Electoral Commission and the Boundary Committee for England.' Henrietta Campbell has also been appointed an electoral commissioner .
