114.Section 20 amends the Greater London Authority Act 1999 so that the existing procedure for the London Assembly to scrutinise senior appointments made by the Mayor applies to the appointment of the Deputy Mayor for Policing and Crime by the Mayor in his capacity as the Mayor’s Office for Policing and Crime. Where the proposed candidate for Deputy Mayor for Policing and Crime is not a member of the London Assembly, the Assembly will have the power to veto the appointment by a majority of two thirds of the members voting.
