A former Hackney Labour councillor on Tuesday admitted possessing indecent images of children.
Thomas Dewey appeared at Uxbridge Magistrates’ Court charged with five offences.
The 36-year-old, from Hampshire, admitted making five category A , the most serious kind, of indecent images of children on April 29, 2022.
On the same date he downloaded four category B and 203 category C images.
He also admitted possessing 78 extreme pornographic images of children and having over 1,500 prohibited images of children in his possession on or before January 20 2022.
Dewey was arrested by National Crime Agency officers at his home in Hackney on April 29, 2022, a week before he was elected a councillor.
Labour were notified on May 16 by the council’s Chief Executive that he had been arrested and he was suspended from the party.
Dewey resigned as a councillor the same day, triggering a by-election last July.
He is due to be sentenced at Isleworth Crown Court on August 15.
