Theresa May cannot ignore the warnings of business and international allies on Brexit disaster

THERESA May tried to put on a brave post Brexit face this weekend

But there’s unease in the east and it will follow her home from the G20 Summit.

The biggest blow was a 15-page warning from Japan that Brexit could hit its investment in the UK - unless access to the European Single Market is maintained.

Japanese car companies such as Toyota and Nissan came to the UK because they got access to the 500 million consumers in the EU’s “single market”, the biggest in the world.

Now their government warns “Japanese businesses with their European headquarters in the UK may decide to transfer their head-office function to continental Europe if EU laws cease to be applicable in the UK after its withdrawal.”

The way things are going, that’s exactly what’s going to happen. Theresa May warns free movement of people will cease - a demand that certainly puts Britain out of that single market.

Her trade minister Liam Fox has already said he thinks the UK will be out of the EU “Customs Union”, meaning massive paperwork for companies moving goods around.

Her actual Brexit minister David Davis just seems confused, unable to tell MPs this week what a deal will look like.

He could do worse than take heed of the “Letter from Tokyo”.
