Dozens of tower blocks expected to fail fire safety tests, ITV News understands
Video report by ITV News Correspondent Angus Walker
More than 60 high-rise blocks across the UK may have failed robust fire safety tests, ITV News understands.
Dozens of tower blocks are expected to fail the tests carried out in the wake of the Grenfell disaster, the results of which are due for publication on Friday.
A Government source has told ITV News that more than 60 blocks may have cladding similar to that used at Grenfell.
But residents living in blocks subjected to tests may not even be told of their results - a decision which rests with tower owners.
It is understood that residents in just nine high-rises - all of which are in Salford - have been made aware their homes are affected.
That cladding has only been partially removed, however.
An initial set of Government tests on the safety of tower blocks, carried out following June's Grenfell fire - which claimed the lives of more than 80 people - produced a 100% failure rate.
The latest tests are more robust and are "vital" to determine which blocks are safe to live in, according to ITV News Consumer Editor Chris Choi.
However, residents living in these tower blocks do not have a "clear right" to receive the results.
Officials told ITV News that building owners would be informed of the results, but it would be up to them to inform tenants and home-owners.

Chris Choi predicted further problems ahead over improving the safety of current high-rises.
While it may become clearer which tower blocks are fitted with the dangerous cladding, what to use as a replacement remains uncertain.
Meanwhile in other tests, hundreds of blocks across England were found to have fire safety flaws, including broken fire doors and holes which could help blazes spread.
Nearly a third of social housing blocks were found to have damaged fire safety doors, 71 with a lack of emergency lighting, and 73 with no safety information for fires.
