'Law change will be my sons' legacy - I hope they're proud of me'
Paul and Jack were due to tell family court officers about their father's behaviour before he killed them
Claire Throssell missed seeing her sons by five minutes. She was on her way back from work when they set off for a visit to see their father.
When police knocked on her door later that night, her first thought was: "What has he done?"
Her estranged husband, Darren Sykes, had started a fire in his home while Jack, 12, and Paul, nine, were inside the attic looking at a train set, then locked them in.
The unsupervised access visit had been sanctioned by the family court despite evidence that Sykes had abused both his sons and Claire, and was capable of harming them.
Paul died on that same night, 22 October 2014, and Jack passed away a few days later, believing he had saved his younger brother's life.
Claire made Jack a promise while he lay in her arms in hospital - and this week she feels like, more than a decade on, she kept that promise.
Claire, from Penistone near Barnsley, has spent 12 years campaigning to change the law around presumption of parental involvement, which assumes children benefit from contact with both parents after separation, and on Tuesday she saw the Courts and Tribunals Bill go through its final stages in the Commons.
That means it will become the law she has spent so long fighting for.
I remember sitting in her front room more than a decade ago, nearly a year to the day after the boys were killed.
