Lichfield and Burntwood MP Michael Fabricant has told Prime Minister David Cameron he did not want to be considered for a government job.
The Prime Minister formed the first majority Conservative government since 1992 after their general election victory.
Mr Fabricant, 64, explained that he felt a senior post would have hampered his ability to fight on local issues.
The MP said: “I told David and his senior officials that I did not want to be considered for a position.
“I want to be free to oppose the HS2 bill when it returns to the House of Commons for its final reading.
“I believe the next five years of government are going to be tough with our majority of just 12.
“As a former Conservative whip, I have told government chief whip Mark Harper that he’ll have to turn his charm meter up to maximum.”
Mr Fabricant also believes the priorities for the Conservatives are clear over the next five years.
He explained: “Scrapping the Human Rights Act and replacing it with a British Bill of Rights, a European referendum in 2017, ensuring no-one on minimum wage pays income tax and increasing the availability of free childcare are all important policies for us to deliver during the next parliament.”
Mr Fabricant was returned to the House of Commons with 55.4 per cent of the vote.
He increased his majority from the May 2010 general election by 500 after winning 28,389 votes.
And the former Conservative vice-chairman admits he was “flabbergasted” by the general election result.
Lichfield and Burntwood residents have been congratulating Mr Fabricant on his election triumph in a variety of ways, he revealed.
The Conservative politician said: “I’m flabbergasted to have increased my majority as a member of the government, especially with the opposition to HS2.
“I’ve had people hugging and kissing me on the street and even in the bank following the election!
“I would like to thank all of the people who voted for me, my election agent Jean Simpson and my team. I’ll continue to represent all of my constituents irrespective of whether they voted for me or not.
“A member of my team claimed that my majority would be cut to around 4,000, he sure got that one wrong.”
