Opponents of grammar schools are to use the return of the Government's controversial Education Bill next week to attempt to abolish the 11-plus.
It could mean the end of Birmingham's eight grammar schools.
MP Lynne Jones (Lab Selly Oak) said: "I expect there to be an amendment to the Bill and if nobody else proposes one, I will do it myself."
Labour dissidents are planning a series of amendments which they will ask the Government to accept in return for their support in the Bill's third reading.
They intend to re-open the issue of selective education, five years after opponents of grammar schools gave up the battle to have them abolished.
Rebel amendments will set an abolition date of 2010 for the 11-plus exam.
After that date, parents will be able to vote in a ballot to restore the exam.
This is the opposite of the system currently in place, which allows grammar schools to continue unless local parents vote in a ballot to abolish them.
In Birmingham, about 50,000 signatures from parents are required before a ballot can take place.
Dr Jones said there was now a consensus that selective education was unfair, as Conservative leader David Cameron had scrapped Tory plans to open a grammar school in every town.
She was criticised by Elspeth Insch, head of Edward VI Handsworth School in Birmingham.
Ms Insch said: "We have always known that they will try to hold the Prime Minister to ransom on this.
"These are people who don't want to widen opportunity. They don't only oppose grammar schools, but any form of diversity in education."
The Education Bill will create a new breed of schools called Trust Schools.
It has proved controversial with Labour MPs because it extends the role of the private sector in state education and only succeeded in its second reading because Conservative MPs voted in its favour. ..SUPL:
