The Conservatives were forced out of their traditional stronghold of Solihull in the most dramatic twist in the seat's 60-year history.
The wealthy borough has been true blue since it was created in 1945, but it changed hands after a fiercely fought election battle which saw the Liberal Democrats win after two nail-biting recounts.
Businesswoman Lorely Burt, aged 50, won the seat with a 279 majority in a shock result which saw John Taylor booted out after 22 years as Solihull MP.
The constituency was seen as one of the safest Tory seats in the country and Mr Taylor won the 2001 election with a huge 9,407 majority.
MPs and party supporters had to wait for the result at North Solihull Sports Centre, in Chelmsley Wood, until after 4am yesterday, when recounts were ordered firstly by the returning officer and then Mr Taylor.
Mother-of-two Mrs Burt said: ?I am absolutely delighted.
?I want to thank the people of Solihull who have put their trust in me. I am aware it is a very small majority and will spend the next four years putting the people of Solihull first.
?This is historic for Soli-hull and we mounted a campaign never seen before and it paid off. I know that it?s a very slim majority, and I will spend the next four years... in serving those people, putting them first in everything that I do.?
She added: ?I would like to pay tribute to Mr Taylor for his 22 years of service he has given to the people of Solihull.?
Solihull was number 55 on the Liberal Democrat?s target list.
Mr Taylor, a former junior Minister at the Department of Trade and Industry, was widely expected to retain the seat. He congratulated Mrs Burt in a brief speech following the result.
?I am disappointed. I congratulate Mrs Burt and trust she will represent the people of Solihull as I have tried to do,? he said.
?It was a great honour to represent Solihull for 22 years. I had not intended to retire, but I guess I just have.? The turnout of 68 per cent was six per cent up on 2001.
