The judge heading the Grenfell Tower inquiry has been urged to stand down by the local MP for Kensington, who says they need “somebody we can trust”.
This follows a call on Monday for Sir Martin Moore-Bick to quit by lawyers representing some of the victims.
Labour MP Emma Dent Coad said Sir Martin was “a technocrat” who lacked “credibility” with the families.
Retired Court of Appeal judge Sir Martin has said he understands the “desire of local people for justice”.
It comes as questions are raised over the efforts being made to rehouse those left homeless by the fire on 14 June.
At least 80 people are thought to have died in the Grenfell Tower fire in North Kensington, west London.
The final toll may not be known until the end of the year, say police.
Ms Dent Coad said: “I have been talking to hundreds of people who have been affected.
“They need somebody they can talk to, somebody with a bit of a human face,” she told BBC Radio 4’s Today programme.
“I don’t think he should do it. I don’t think there will be any credibility.
“Some people are saying they are not going to co-operate with it, so it’s not going to work.”
There has been widespread criticism of Sir Martin following his appointment.
Local residents have questioned whether his background in commercial law was appropriate.
They have also been angered by his decision to allow Kensington Council – who was criticised for its slow and ineffective response to the disaster – to contribute to the inquiry.
