Keith Vaz, who has chaired the Commons home affairs select committee for over eight years, is reported to have removed both his Twitter and Facebook pages after being inundated with abusive messages.
Why would the most attention-seeking MP this side of the Milky Way suddenly close his account on Twitter?#KeithVaz— Dame Alun Roberts (@ciabaudo) January 6, 2016
The MP for Leicester East came under the spotlight earlier this year for defending the now deceased former peer Greville Janner against child sex abuse allegations.
Lord Janner, who died in December aged 87, was accused of 15 counts of indecent assault and seven counts of a separate sexual assault against a total of nine alleged victims in spanning three decades.
Vaz, 59, defended Janner back in 1991, saying his friend had fallen victim to a "cowardly and wicked attack by people who simply did not care what damage they did to him."
But on Thursday, social media users were quick to theorise about why Vaz could have terminated accounts that had thousands of followers.
