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.
Work based VPNs would likely have to obtain a license from Ofcom, it would be highly unlikely to block them completely. Probably be requesting a back door into the work VPNs at the same time just like they have for other encryption, lol.
