Parliament has been hit by a cyber-security attack, said Liberal Democrat peer Baron Rennard.
The attack has been described as ‘sustained and determined’.
Some MPs have admitted having difficulties accessing their emails.
Lib Dem peer Lord Rennard said on Twitter: ‘Cyber security attack on Westminster Parliamentary e-mails may not work remotely text urgent messages.’
While Chi Onwurah, MP for Newcastle Central and Shadow Minister for Industrial Strategy and Innovation advised constituents to contact her via a Gmail account, advising the problem looked unlikely to be resolved until at least Monday.
At present, it’s known that parliamentary emails cannot be accessed outside Westminster although little else in known about the hack.
The cyber threat follows reports that passwords for MPs and officials were being sold online by hackers.
A House of Commons spokeswoman said: “The Houses of Parliament have discovered unauthorised attempts to access parliamentary user accounts.
‘We are continuing to investigate this incident and take further measures to secure the computer network, liaising with the National Cyber Security Centre.
‘We have systems in place to protect member and staff accounts and are taking the necessary steps to protect our systems.’
