Tenants who illegally sublet flats in Grenfell Tower have been urged by the government to come forward to give grieving families "closure".

Communities Secretary Sajid Javid made the appeal after top prosecutors confirmed people would not be charged for coming forward to help the emergency services learn the true death toll.

Officials expect it to take months to learn how many more victims perished along with the 80 people currently known to have died in last month's unprecedented fire.

Speaking in the House of Commons, Mr Javid said: "There may have been people living in flats that were illegally sublet who have no idea about the true status of their tenancy.

"Their families want to know if they perished in the fire. These are their sons, their daughters, their brothers, their sisters. They need closure and it's the least that they deserve.

"But that can't happen unless we have the information we need, so we are urging anyone with that information to come forward and to do so as quickly as they can."

Mr Javid faced scrutiny as he confirmed all the survivors of last month's unprecedented west London blaze will have been offered temporary accommodation by Wednesday.

Shadow housing secretary John Healey asked him how many people were still in hotels and if the promise of a "good quality" temporary home included hotel rooms.

Mr Javid said the hotels were classed as emergency accommodation, while temporary accommodation could be houses or flats or "whatever is the choice of the resident".

"I want to make sure they have high-quality accommodation offered to them that's appropriate for their family type and their family size," he told MPs.

"But they will not be forced, and should not be forced, to accept accommodation that they do not want to move into at this point."

Mr Javid also said the offer to all survivors of accommodation by midweek would meet Theresa May's pledge to rehouse those affected within three weeks.

However, Mr Healey accused ministers of being "off the pace at every stage" since the fire and "too slow to grasp the scale of the problems people are facing and too slow to act".

Mr Javid, who was speaking during an urgent statement, also announced all 181 samples of cladding so far tested after Grenfell have failed fire safety tests.

He said the finding was "disturbing" as he urged landlords to prioritise making buildings safe and to provide alternative accommodation while work is being carried out.
