France's former environment minister Delphine Batho, who was sacked on Tuesday, has blamed the fracking and nuclear power industries for her dismissal.

Ms Batho, who held the energy and the environment portfolios, was fired by President Francois Hollande after she called his 2014 spending plans ''bad'' because they cut her department's funds by about 7 per cent.

Mr Hollande announced her sacking via Twitter.

But Ms Batho said on Thursday that her support for France's ban on shale gas drilling and reducing its dependence on nuclear power were the real reasons behind her departure.
