It seems that the British Prime Minister Theresa May has done the impossible and bridged the Brexit gap. 

No, not the gap you might expect by two sides sitting across from one another as part of a complex negotiation.

The bridge building which took place in Mrs May’s Mansion House speech was between the two sides in her own party. 

That in itself sums up a lot of the problem with the route which Brexit has taken so far in the UK. 

A significant proportion of the struggle to define Brexit and agree on the way forward has not been between the British government and the EU Commission, but between the entrenched views of the Remain and Leave wings of the Conservative Party.  

There has been a cautious welcome for Mrs May’s speech from many of those who might have been expected to react badly. 

For the first time there was a public acknowledgement from the Prime Minister that Brexit will be complex, difficult and may result in compromises some will find difficult - compromises some might have found impossible just weeks ago. 

MP’s such as Jacob Rees-Mogg, an arch Brexiteer who is being touted as a possible future Conservative Party leader, described the speech as "sensible, pragmatic and generous". 

His opinion matters since many in his party now look to him as an arbiter of whether Mrs May is sticking to the complete Brexit they seek.  Mr Rees-Mogg has in the past advocated walking away from a deal which does not represent a total break from the EU.

When Theresa May uttered the phrase in her Lancaster House speech in January  2017 "no deal is better than a bad deal" there was an audible gasp in the room. She may have repeated that phrase in the Mansion House, but this time it was when asked a direct question about it. 

Instead, her speech was peppered with phrases which suggest that is not the way she wants to go now. 

Her talk is of getting a deal done, and in doing so she had to prepare the ground for the inevitable compromises which will have to be accepted and the red lines which will have to be crossed.

Mrs May is dealing with negotiations on many fronts - with the EU Commission as she tries to untangle 45 years of deeply ingrained economic and political ties. 

With her own party as her weakened leadership tries to bring together the two sides in a debate which has torn the Conservative Party apart for years. 

With a Parliament which is two thirds in favour of staying within the European Union. 

With a public, many of whom are weary of the time and energy which Brexit is taking from other areas of public life such as the National Health Service.

One of those who is all too aware of Mrs May’s predicament was out this week to give a significant speech of his own on Brexit. 

Sir John Major’s premiership was dominated by Conservative Party rows about Europe.  Advocating a free vote in Parliament on the final Brexit deal, he said that a second referendum should be a possibility. 

He urged Theresa May to stand up to the hardline Brexiteers within her own party who he said "were boxing the government into a corner". 

If Mrs May is in a corner though, many arguments could be made about how she got there. 

Was it the overall lack of any planning for the possibility of a Leave vote in the referendum? 

Was it an early failure to define a vision of Brexit and instead use soundbites such as "red, white and blue Brexit" and "Brexit means Brexit" which said nothing and left a vacuum in which everyone could place their views? 

Or was it the decision to call an early election in which the Conservative Party lost its majority and which weakened Theresa May and any authority she might have to stand up to those who wanted to sway her opinion?  

For now at least Theresa May seems to have brokered an uneasy peace in her party. 

But let’s not forget that there was no significant new detail in that speech on key areas such as Northern Ireland and how - exactly and precisely - a hard border could be avoided. 

And for all the suggestions made by Mrs May on issues such as passporting rights for London’s financial sector or continued recognition of European agencies in medicines and aviation, none of this has yet been agreed by the EU 27.

There are plenty of bridges yet to cross.
