The UKs ruling Conservative Party have lost 2 of 3 by elections that took place in England.
Critics say it shows how unpopular the Government and their policies are. The next general election is expected to be held next year, with the Conservatives a long way behind in the polls.
They did narrowly manage to retain the seat vacated by former Prime Minister Boris Johnson - it's thought a controversial local issue about emission zones introduced by the Labour Mayor of London was the reason they managed to hold on.
Meanwhile in Somerset and North Yorkshire, the Conservatives lost seats that previously had huge majorities of around 20 thousand.
Tim Bale - professor of politics at Queen Mary, University of London - says it's a bruising set of results for the government:
In: We have to…
Out: …can press on.
