After being recognised locally for helping to pass 'Sian's Law' the mother of Sian O'Callaghan says that she and her family are not done yet. 

At just 22 years old, Sian was murdered by taxi driver Christopher Halliwell in March 2011 after he picked her up in his cab from a night out. 

As a result, Sian's mother Elaine Pickford and her family spent four years campaigning for more regulation of taxi drivers and successfully saw the bill she was fighting for becoming a new law. 

This was why Elaine was one of many local heroes who were celebrated at the BBC Make a Difference Awards earlier this month.

But following the award win, Elaine says that there is still more work to be done to make people safer as she and her son Liam are soon to meet with the Suzy Lamplugh Trust to discuss campaigning to bring in further legislation. 

She said: "This [Taxi and Private Hire Vehicles (Safeguarding and Road Safety) Bill] is an element of it. It means local authorities need to share information about driver applications, so if someone applies for a licence in Swindon and gets refused and then tries to reapply in Somerset at a different authority, it will be flagged up. And it has to be shared within a certain timeframe. 

"But further improvements are needed.

"The Suzy Lamplugh Trust got in touch with Liam, one of my eldest sons, and I just before the awards and wanted to know if he and I would be happy to be involved and we said yes, of course.

"We are yet to have that meeting and are working out a date but we hope it will be soon."

"It was great to receive it, but for me, the most important part was the law being passed.

"I do want to thank the community from the family and me, as I know more than anyone what community means after the way it came together for me in 2011.

"But at the same time, and I was naughty and gave a little speech, I almost wanted to say that I shouldn't be doing any of this," she said, "Because Sian should still be here."

"It's like something walks beside you, and I feel that Sian does as well, and it's something that we all feel all the time and manage in different ways,  Sian’s siblings have their ways. But she was a supportive and caring person, we all know that she would want us to endeavour to get on with our lives and she would certainly be in support of what we're doing to make things safer for people.

"Ultimately, seeing that bill pass, was an emotional moment and a testament to Sian - a lasting legacy to Sian."

Personal safety charity the Suzy Lamplugh Trust, which was set up following the disappearance of 25-year-old estate agent Suzy Lamplugh, supported the family's campaign at the time. 

It became a private members bill after being introduced by Darlington MP Peter Gibson, who said: "I'm going to call it Sian's Law because it's a way to remember Sian and pay tribute to the work that Elaine has done along with the Suzy Lamplugh Trust," he added.

"It closes that loophole...so that bad people who we don't want driving taxis can't circumnavigate the system."

Halliwell, 59, was jailed for life in October 2012 for the murder of Ms O'Callaghan.

He was later handed a whole-life sentence for the murder of Becky Godden from Swindon.
