Sadiq Khan has awarded a salary raise to some of his top aides, including one already on a higher wage than the Prime Minister, according to information published on the London Assembly website.

Following the decision, which was made by the Mayor earlier this month, the pay rises awarded to GLA staff could cost the taxpayer just under £600,000 a year.

As part of the pay award, Sadiq Khan has extended the raise set for GLA staff on lower pay grades to senior mandarins and mayoral appointees that already enjoy six-figure salaries.

Jeff Jacobs, the Head of Paid Service at City Hall, is one of the staffers in line for the hand-out. He currently takes home more than £170,000 per annum, making his salary almost £20,000 higher than the Prime Minister’s.

David Bellamy, the Mayor’s chief of staff, will also be looking forward to a salary hike. He is currently salaried at £131,901 according to the London Assembly website.

GLA staff on lower pay grades will also be receiving a two per cent pay award, while staff on average pay grades receive a 1.5% pay rise. Senior staffers will be given an inflationary one per cent raise.

John O’Connell, Chief Executive of the TaxPayers’ Alliance, said: “The Mayor will need a competent team to help him see through his policy agenda and that will require paying some staff well.

“But taxpayers will struggle to understand how it is that this particular clutch of public sector workers are not subject to a pay cap like many other areas of the public sector have been.

“With the nation’s books far from balanced, pay restraint is essential across all arms of the state and Sadiq Khan must explain why he believes his staff are immune from such measures.”

A spokesperson for the Mayor of London, said: “The Mayor is determined to lead the way as a model employer, adopting the highest possible standards for fair pay, good working conditions and gender equality.

“In line with local and central government pay rises, The Mayor and London Assembly agreed to the award of a one per cent increase for City Hall staff, with an additional one per cent or 0.5 per cent for staff on the lowest pay grades, to reflect the increased cost of living in London.”

The pay award to GLA staff is to be funded from the authority’s contingency budget.
