Theresa May could push through extreme internet regulation while people are distracted by the current political situation, according to activists.
The prime minister might look to automatically censor the internet, for instance, and weaken security in a way that "could put all of us at a great risk of crime", it said.
Despite failing to win a majority at the recent election, Ms May has suggested that she will keep going with her extreme plans. And she might do so specifically because the government's majority is "fragile", he said.
Such decisions would help make Ms May look strong and serve as a distraction from the current political situation, including the lack of a majority in parliament and the Brexit negotiations. But they might serve only to put people in danger, he said.
“To push on with these extreme proposals for Internet clampdowns would appear to be a distraction from the current political situation and from effective measures against terror," said Jim Killock, Open Rights Group's executive director.

Such changes are not necessary because the government already has sweeping surveillance powers, Mr Killock warned. Instituting them may only have the effect of making life easier for terrorists, he said.
"Both of these proposals could result in terrorists and extremists switching to platforms and services that are more difficult for our law enforcement and intelligence agencies to monitor," he said.
And the concentration on other issues may go through while parliamentarians and the public are distracted.
"Given that the priority for all MPs is how the UK will negotiate Brexit, it will be especially hard to give the time and thought necessary to scrutinise these proposals," he said.
"It could be tempting to push ahead in order to restore some of Theresa May’s image as a tough leader. This should be resisted. With such a fragile majority, greater consensus will be needed to pass new laws.
"We hope that this will mean our parliamentarians will reject reactionary policy-making and look for long-term, effective solutions that directly address the complex causes of terrorism."
Organisations including the PSNI, Food Standards Agency and the Department for Work and Pensions will be able to see UK citizens' entire internet browsing history in weeks.
The Ministry of Defence’s former cyber security chief has accused the Government of trying to “use” the devastating Westminster attack to grab unnecessary and intrusive surveillance powers.
The Investigatory Powers Act is an “assault on freedom” quietly passed by the British government while people were afraid and distracted, according to campaigners.
The Republican nominee has been attacked for his approach to the internet in the past. Earlier this year he said that he wanted to “close up” the internet, and that he would speak to powerful people including Bill Gates about doing so.
