Prominent backbench MP Sarah Champion launched a campaign against VPNs previously, saying: “My new clause 54 would require the Secretary of State to publish, within six months of the Bill’s passage, a report on the effect of VPN use on Ofcom’s ability to enforce the requirements under clause 112.
"If VPNs cause significant issues, the Government must identify those issues and find solutions, rather than avoiding difficult problems.” And the Labour Party said there were “gaps” in the bill that needed to be amended.
I am pretty sure they would consider tor as using a VPN.
Probably they would demand ISPs to run lists of known VPN addresses and if you connect to them, they will forward the information to the anti-terrorism unit and you will get SWATed.
