UK not to pay financial settlement if there is no trade deal - The Telegraph

" Britain will not pay its agreed £39 billion bill to leave the European Union if a trade deal cannot be agreed, Theresa May has told her MPs," The Telegraph reported in an article on Monday. 

Key quotes from May's letter to her party:

The Government has said that we are a country that honours its obligations, and that is what we will do.

We have agreed a fair settlement of commitments we have made while a member of the EU, in the spirit of our future partnership.

It depends upon a broader agreement being reached – as I have said, nothing is agreed until everything is agreed – so if there is no agreement then our offer also falls away.
