"It will be the first time we have brought together MPs, whistleblowers, the survivors and child protection professionals. There are individuals coming from scores of survivors groups across the country – survivor support groups, survivor campaign groups," Phil Frampton, a campaigner who will chair the meeting, told the newspaper.
Around 30 victims' groups will be represented at the meet.
According to Frampton, more than 200 people are expected to attend the rally. "The aim is to bring together a coalition of people, which the Government hasn't done effectively to put our heads together, look at things from different angles and consider strategy for the future," he said.
The meet was organized with the help of John Mann, the Labour parliamentarian who wrote to all party leaders last month, encouraging them to "put all other considerations aside and urgently uncover and pass on any information relating to child abuse."
Following Mann's letter, the UK Prime Minister David Cameron agreed to open the Conservative Party's central office and the party's office of whips, which monitors the indiscretions of members of parliament, for an investigation, The Telegraph reported.
