The news has sparked outrage from opposition parties in the London Assembly, and Johnson has added fuel to the fire by stating there will be further appointments of deputy mayors.
According to the Green Party, Johnson has claimed the ‘more deputy mayors, the merrier’, and also added that he ‘can’t be expected to dot the "i"s and cross the "t"s of all planning decisions’.
Green Party London Assembly member Jenny Jones said: ‘Londoners expect the person who they elected as Mayor to make major decisions on planning himself and not leave these to an unelected, unaccountable appointee.
‘If Mayor Johnson is so overstretched, then why is he taking on a £250,000 contract to write a regular column for the Daily Telegraph?’
Jones added that the mayor will be expected to take ‘hugely controversial’ decisions to meet the housing demands of the capital.
‘These are huge, strategic planning decisions affecting the building of tens of thousands of homes and offices,’ she said. ‘These will give rise to major community campaigns involving hundreds or even thousands of people.
‘The decision-making process should be transparent and that means Londoners need to be clear who is making the final decision,’ Jones added.
