Conservative Alma Thrower is the new Councillor for Hutton Ward in Guisborough after a fantastic by-election victory in which she secured well over half the total votes cast.
The full results were as follows, with changes from the 2015 election in brackets:
CON: 57.4% (+3.6)
LDEM: 21.8% (+4.4)
LAB: 12.2% (-16.6)
UKIP: 8.6% (+8.6)
Alma, who is currently serving as Mayor of Guisborough on the Town Council, will now take up her seat on the Borough Council.
Conservative Parliamentary spokesman Simon Clarke said, "Alma will be a great champion for Hutton Ward and congratulations to all the team at South Tees Conservatives who helped secure this result - it's a real vote of confidence and further proof of how the divided and out of touch Labour Party is losing support in Middlesbrough South and East Cleveland."
