• UKIP has hammered the Conservatives and Lib Dems in Rotherham winning a massive 21.79% in yesterday's poll, just a fortnight after earning a record 14.3% in the Corby by-election.
Party Leader Nigel Farage said: "This clearly shows that UKIP's policies are connecting with the people."
UKIP candidate Jane Collins won 4,648 votes to come second behind Labour's Sarah Champion with 9,866. Yet again, the Lib Dems lost their deposit.
There were 11 candidates standing in the by-election and the turnout was 33.8% - down from 59% in the 2010 general election.
The by-election was called following the resignation of the former MP Denis MacShane on 2 November.
Meanwhile, UKIP scored another strong result in the North East where Richard Elvin took second place in Middlesbrough, again behind Labour.
The Party won 1,990 votes – 11.8% – to Labour's 10,201, with the Lib Dems coming third with 1,672 and the Tories limping into fourth place on just 1,063, just three votes ahead of the Peace Party candidate.
Mr Elvin said the result proved there was a desire for change.
"There can be no doubt that UKIP is on the up," he said.
"UKIP is now the only political party which we can truly say can take the fight to Labour in the North East."
The Middlesbrough by-election was triggered by the death of sitting Labour MP Stuart Bell from pancreatic cancer.
In the third by-election result of the night, UKIP's Winston McKenzie took third place in Croydon North with 5.7% – 1,400 votes– seeing off the Lib Dems with just 860 votes and Respect, whose Lee Jasper won just 707 votes.
Labour's Steve Reed secured 15,898 votes - 64.7% of those cast - with Andy Stranack of the Conservative Party in second place on 4,137 votes. The Labour party had been widely expected to retain the seat in the by-election which was called after the death of popular Labour MP Malcolm Wicks in September.
