In December 2017, when Ms May and the EU finally found an agreement about the first part of the Brexit negotiations, many thought  that it  would bode well for the future. Nevertheless, difficulties on both sides keep multiplying to make reaching  mutual agreement difficult on almost every detail of Brexit’s consequences.
First, the deal of December 2017 forecasts that the UK is due to pay about 50 billion to the EU to comply with the charge it had promised to pay before Brexit happened. Secondly, Ms May announced that the European foreign workers in the UK could continue to live like before Brexit and must not worry. Last, the EU and the UK reaffirmed that it would not have a new material border between Northern Ireland and Eire.
Nevertheless, that first agreement appears quite insubstantial and not very concrete. More worryingly, Ms May and Europe keep rejecting their mutual proposals and are unwilling to make compromises. For instance, Ms May fiercely rejected the deal on 28th February proposed by Michel Barnier, the European Brexit negotiator.  His main measure suggested that the UK would stay in the European custom Union to solve the problem of the Irish border.
It also must not be forgotten that the negotiations will end in March 2019, date of the expected official separation between the UK and the EU. The timescale seems to be very short for Ms May to negotiate a satisfying trade-deal for her country. Indeed, all European countries demonstrate an unexpected unity when it comes to negotiating the trade deal and defend strong and solid positions, refusing to grant the UK any privilege.
Thus, if Ms May keeps saying she wants a “loud and clear” break with the EU after Brexit, the reality could go beyond her expectations, and put the UK in danger owing to too drastic a change for the country.

In December 2017, when Ms  (need a full stop for mr. mrs. ms.)May and the EU finally found an agreement about the first part of Brexit’s negotiations, many would think that would bode well for the future. Nevertheless, difficulties of both Ms May and the EU keep (changed some of the tenses to past tense)multiplying to reach mutual agreements on almost every detail of Brexit’s consequences.
First, the deal of December 2017 forecasts that the UK is due to pay about 50 billion to the EU to assume the charge it had promised to pay before Brexit happened. Secondly, Ms May announced that the European foreign workers in the UK could continue to live like before Brexit and must not worry. Last, the EU and the UK reaffirmed that it would not have a new material border between Ireland and Eire.
Nevertheless, that first agreement appears quite tinny and not very concrete. More worryingly, Ms May and Europe keep rejecting their mutual proposals and are little ready to make compromises. For instance, Ms May fiercely rejected the deal on 28th February proposed by Michel Barnier in charge of the Brexit’s question for Europe. His main measure suggested that the UK would stay in the European custom Union to solve the problem of the Irish border.
It has also not to be forgot that the negotiations will end in Mars 2019, date of the expected official separation between the UK and the UE. The delay seems to be very short for Ms May to negotiate a satisfying trade-deal for her country. Indeed, all European countries demonstrate an unexpected unity when it comes to negotiate the trade deal and defend strong and solid positions, refusing to grant to the UK any privilege.
Thus, if Ms May keeps saying she wants a “loud and clear” break with the UE after Brexit, the reality could go over her expectations, and puts the UK in danger owing to too hard and fast changes for the country.

In December 2017, when Ms. May and the EU finally found an agreement about the first part of Brexit’s negotiations, many would think that would bode well for their future. Nevertheless, difficulties to reach mutual agreements on almost every detail of Brexit’s consequences, for both Ms. May and the EU, kept multiplying.

First, the deal of December 2017 forecast that the UK is due to pay about 50 billion to the EU to assume the charge it had promised to pay before Brexit occurred. Secondly, Ms. May announced that the European foreign workers in the UK could continue to live as they were before Brexit and must not worry. Last, the EU and the UK reaffirmed that it would not have a new material border between Ireland and Eire. 

Still, that first agreement appears quite devoid and not very concrete.  Disconcertingly, Ms. May and Europe keep rejecting their mutual proposals and are little ready to compromise. For instance, Ms. May fiercely rejected the deal on the 28th February proposed by Michel Barnier in charge of the Brexit’s question for Europe. His main measure suggested that the UK would stay in the European custom Union to solve the problem of the Irish border. 

It has also not to be forgotten that the negotiations will end in March 2019, which is the date of the expected official separation between the UK and the UE. The delay seems to be very short for Ms. May to negotiate a satisfying trade-deal for her country. Indeed, all European countries demonstrate an unexpected unity when it comes to negotiating the trade deal and defending strong and solid positions, refusing to grant to the UK any privilege. 

Thus, if Ms. May keeps saying she wants a “loud and clear” break with the UE after Brexit, the reality could go beyond her expectations and put the UK in danger due to hard and fast changes in the country.

In December 2017, when Ms May and the EU finally came to an agreement about the first part of Brexit’s negotiations, many would think that this would bode well for the future. Nevertheless, difficulties on both Ms May and the EU's side keep multiplying, making it hard to reach mutual agreements on almost every detail of Brexit. 
First, the deal of December 2017 forecasts that the UK is due to pay about 50 billion to the EU to assume the charge it had promised to pay before Brexit happened. Secondly, Ms May announced that the European foreign workers in the UK could continue to live as before Brexit and must not worry. Lastly, the EU and the UK reaffirmed that there would not be a new physical border between Ireland and Eire.
Nevertheless, that first agreement appears quite flimsy (tinny is a sound) and not at all concrete. More worryingly, Ms May and Europe keep rejecting each others proposals and are hardly ready to make compromises. For instance, Ms May fiercely rejected the deal on 28th February proposed by Michel Barnier in charge of the Brexit’s question for Europe. His main measure suggested that the UK would stay in the European Union to solve the problem of the Irish border.
It must also not be forgotten that the negotiations will end in March 2019, the date of the expected official separation between the UK and the UE. The remaining time seems very short for Ms May to negotiate a satisfying trade-deal for her country. Indeed, all European countries demonstrate an unexpected unity when it comes to negotiating the trade deal and defending strong and solid positions, refusing to grant to the UK any privilege.
Thus, if Ms May keeps saying she wants a “loud and clear” break with the UE after Brexit, the reality could overshadow her expectations, and could put the UK in danger, owing to too hard and fast changes for the country.
