She was one of 10 rebel MPs to be brought back into the Conservative fold by the Prime Minister ahead of the campaign for the next general election.
The Stourbridge MP had been one of 21 Tories to have the whip withdrawn after rebelling against the Government in a Commons vote on Brexit in December.
At the time she said the Conservative Party was transforming into the Brexit Party under Mr Johnson and was not fit to govern in its current state.
She is now expected to contest the Stourbridge seat she has held since 2010 for the Conservatives at the forthcoming election.
Mr Johnson is believed to have selected the 10 MPs to readmit based on their records in supporting key Brexit votes since the mass expulsion.
The others to be readmitted are: Alistair Burt, Caroline Nokes, Greg Clark, Sir Nicholas Soames, Ed Vaizey, Richard Benyon, Stephen Hammond, Steve Brine and Richard Harrington.
In the Commons last night MPs backed a December general election.
