Caroline Curry, whose son Liam Curry, 19, was killed in the bombing, said she was “devastated” about amendments to the bill and felt like she had been misled.
“We can’t bring our children back, they’re gone,” she said.
“But what we can do is try to stand up for other people and try to protect their children.”
“It’s not what they agreed and what they promised,” said Lisa Rutherford, whose daughter Chloe Rutherford, 17, was also killed.
“They have said that they will go away and have another look but we are not hopeful,” she added. “All we want is honesty.”
“The government is in danger of snatching defeat from the jaws of victory,” said Pete Weatherby KC, a director of the Hillsborough Law Now campaign which is assisting with the bill.
At Prime Minister’s Questions, Labour MP Anneliese Midgley accused MI5 of spending “six years misleading the public and concealing information” about the arena bombing.
In response, Sir Keir said he is determined not to “water down” the legislation and argued that the amendments tabled by the government would “strengthen” it.
“It is right that there are essential safeguards in place to protect national security, and we’ve got that balance right,” Starmer said at PMQs.
