Sadiq Khan has written a letter to Theresa May, hitting out at the “dismal lack of action taken by the government”.
In the letter, he also calls for the next Prime Minister to make tackling the “injustice in our society” a priority.
Khan, wrote: “On 14 June 2017, a fire broke out in Grenfell Tower resulting in the tragic loss of 72 lives and devastating the community of North Kensington. At that time, your Government pledged that no one would be asked to live in unsafe homes and to take action to prevent such a disaster happening again.
“The reality is that two years on from this tragedy the dismal lack of action from your Government has been utterly shameful and you have failed to deliver on your commitments. Seventeen households remain in emergency and temporary accommodations.
“The community continues to feel ignored and neglected, having to fight for every piece of support from the council – from receiving legal advice, accessing mental health services to simply understanding their rights.
“In addition, the failed building regulations system remains largely unchanged.
“Thousands of people across the country are still living in homes wrapped with unsafe cladding and worry how they are going to cover the costs for making those homes safe.
“And the response to the social housing green paper, lauded as the Government’s answer to the institutional indifference that social housing residents have faced for years, is still not published. This is unacceptable.
“The safety and well-being of Londoners is my top priority. I regularly meet with the bereaved, survivors and residents of Grenfell Tower and the wider community, including businesses that were affected by the fire. In December 2018, I visited Kensington Aldridge Academy (KAA) to announce a £50,000 donation to a Trust for KAA students.
“After meeting with business tenants of Transport for London, affected by the Grenfell Tower fire, I made available a relief scheme to help them recover from the disaster.
“But my powers as Mayor are limited, and I do not have a role in designing and implementing the changes your Government promised, nor in delivering the services desperately needed by the bereaved, survivors and local residents.
“As we approach the second anniversary of the fire, the Government must listen and step up its action.”
As part of the letter, Khan highlighted the 17 households still in emergency and temporary accommodation.
He concluded: “At the start of your premiership, you spoke about tackling injustices in our society. Two years later we are still a long way from achieving justice and reforms.
“Your claim that your response to Grenfell was one of your biggest achievements as Prime Minister is far from the truth, rather it is a legacy of your premiership that vulnerable people in our society have been let down, been continuously neglected and clearly ignored.
“Whoever replaces you as Prime Minister must make it a priority to act on the issues raised in this letter. We owe it to the 72 people who tragically lost their lives at Grenfell Tower, their families, friends and the Grenfell Tower community.”
