British Prime Minister Theresa May said on Friday she would stay on as leader to provide stability after a former chairman of her Conservative Party said he had garnered the support of 30 lawmakers who wanted her to quit.

May is trying to face down a rebellion by some of her own lawmakers just as Britain enters a crucial stage in Brexit talks, 18 months before the country leaves the European Union and must redefine its place in the world.

Some Conservative plotters say her authority is shattered beyond repair after a disastrous speech at her party's conference, which comes after she called a snap election and lost her party its majority in parliament.
