Tory MP Michael Fabricant has been sacked as vice-chair of the party after criticising the HS2 rail scheme and Maria Miller over her expenses.
The former Conservative whip claimed on Twitter that he refused to resign so was sacked by party chairman Grant Shapps.
After news of Mrs Miller's resignation broke, the MP said: "Well, about time."
Mr Fabricant, MP for Lichfield in Staffordshire, tweeted this announcement:
Been asked to resign as Vice Chairman, refused, so sacked over HS2 and my views on a recent Cabinet Minister. Still available 4 speeches etc
After Mrs Miller resigned over her expenses scandal, he tweeted:
Note to self: If ever a minister again, be like Mark Harper. If in trouble, resign quickly & in a dignified manner. Lesson to us all.
He is set to lead a Tory revolt against the £50 billion HS2 scheme later this month by calling for laws so the London-Birmingham is denied a second reading in Parliament.
The MP has spoken of his shock at being sacked and wrote on Twitter:
