Theresa May comments in response to the resignations earlier

UK May
  • Conservative party will offer decent, moderate and patriotic politics
  • Implementing Brexit decision of the people is the right thing for the country

I wouldn't expect her to comment too much on the matter. For now, this is but a minor dent of confidence in her government. Should it start to lead to something bigger i.e. more resignations then we can start talking about a potential breakdown in the UK political landscape.
