It was thoughtless of the Dutch to arrive in our waters with their huge factory ship the Margiris so close to the PM’s leaving date from the EU, as if to hoover up as much of our fish as possible before we leave.

This vessel can catch and process 250 tonnes a day. It was barred from Australia owing to its size and possible impact on their fishing ground. The ship and its nets are designed, we are told, to target pelagic species. The ship is guided by radar to the shoals, and we are assured the nets do not scrape the bottom damaging the sea bed. We are also told this vessel was fishing entirely legally under the rules of the EU’s Common Fishery Policy.

Other large factory ships with nets that do drag the bottom can do grave damage to the sea bed and the marine environment. These vessels can catch a lot of fish very quickly and may sometimes catch species of fish in low supply which we want to be left to allow recovery of stocks.

The practice of dragging heavy and strong nets across the sea, especially if close to the sea bed, can drag up many species you do not want to catch at the same time as the ones you wish to attract. If the net size is too small it can catch and kill young fish. The net can damage the sea bed and general environment if lowered too far.

Once we have left the EU we will be able to set our own standards for net size, size of vessel, and impact of fishing style on the marine environment. It is another great argument for just leaving on 31 October and for  not making our fish any part of continuing negotiations over our future trade relationship. Mrs May’s unpopular Withdrawal Agreement left our fish at risk.

On Monday during the Manchester conference I  talked again to the management of Heathrow airport concerning aviation noise over the Wokingham constituency.

They told me of the progress they are making with encouraging quieter jets and better flying techniques and operating practices to try to control noise, in line with suggestions I have advanced before in discussion with them. 

They also gave me the bad news that there is a further delay in reconsidering the current routes over the constituency, where changes were  imposed without consultation but  are now subject to extensive consultation to try to amend them.  

They agree that people need respite from aircraft noise, and accept that noise is particularly bad when they are operating in easterly winds. They will call for more evidence from local people as they approach making more changes. In  the meantime I think it most important people adversely affected by noise should always use the Noise complaint line for Heathrow to remind them of the continuing dislike of what they have done.  

The World Trade Organisation is body designed to lower tariffs and enforce the common global rules on trade to the benefit of consumers. It is a blow when after long and careful deliberation and investigation it feels it has to make a judgement which entails another country imposing tariffs on a trading counterparty.  That is what happened this week thanks to the behaviour of Airbus and the EU.

The WTO found that Airbus had received  subsidies that broke the rules of fair trade, which in turn had cost Boeing sales of planes. They therefore have allowed the USA to impose tariffs on goods up to a value of $7.5bn which reflects their calculation of the amount of sales damage done to the US company. The USA has decided to impose a 10% tariff on Airbus planes, which will hit future sales. The UK makes the wings for these products.

The USA has also chosen some high profile food and drink products from EU countries for a 25% tariff. This  includes Scotch whisky, which is particularly unwelcome.  It is a reminder that the EU which makes us impose high tariffs on food and drink from non EU parts of the world can through its wider policies end up costing us exports in these same areas as countries impose retaliatory tariffs.

None of this is helpful at a time of manufacturing downturn. There is already an intense tariff based trade spat between the USA and China. The refusal of the EU to lower its high 10% tariff against non EU cars is also a continuing sore with the USA which charges only one quarter of that level on EU cars. The danger is this WTO judgement will take us closer to a broad based trade war between the USA and the EU, just as we have seen develop with the USA and China.

The three features I like most about the UK proposals are

1. The whole UK leaves the Customs Union
2. Great Britain  leaves the single market
3. Northern Ireland leaves the single market unless Stormont meets to vote to stay in

This is in accord with what both sides said in the referendum, that leaving the EU means leaving the single market and customs union at the same time.

It turns out these are the three key features of the proposals which the EU dislikes and  now wishes to remove or water down.

The Prime  Minister was right to say this offer represented still  more UK concessions on other things and they should not expect  more concessions . I  recommend stressing the free trade offer within the letter, which could change the nature of the discussions, given the problems with the draft Withdrawal Agreement and costly and cumbersome so called transition period. .

The latest figures from German industry point to a continuing recession, with substantial falls in orders from the peaks last year. The US is still stronger, but even there the forward indicators are now in negative territory suggesting a downturn. As forecast here we are living through a nasty world manufacturing downturn.

I do find it bizarre that a few people write to tell me the UK share index has gone down this week owing to Brexit, when all the world share markets are flashing red over global events led by EU manufacturing figures.

What can the authorities do about it?

The first thing they need to do is to review their policies towards the vehicle market. There is a gap between what the governments want people to buy and what they are prepared to buy. The big transition from diesel and petrol to electric is proving difficult to achieve at the pace the governments want, leading to a shortfall in demand. As the governments want to intervene extensively  in  this market they need to help the industry adjust.

The second thing is to examine other areas where demand is falling short or capacity is too extensive and see if government itself can speed transition to new products or can stimulate demand for things that are still needed and valued.

General demand for industrial products is affected by numbers in employment, by levels of income, and the impact of taxation. India is now joining the USA with a large reduction in company taxation to act as a stimulus to investment and activity. China has introduced some tax cuts to boost consumer demand. The US and UK have good recent records at increasing employment and real incomes, which should help.

Some believe further monetary activism could assist. Clearly if home loans, car loans and other consumer credit is readily available to those who can afford it, at low interest rates, it should help demand. The US car market looks as if it is improving following interest rate cuts. However, in the Eurozone and Japan official rates are already at or below zero so there are limits to how much monetary action can achieve. The UK does have a severe monetary squeeze which is helping slow our economy.

Those who write in saying we should not borrow more should remember that borrowing is an important part of an enterprise economy. Of course it should not be taken to excess, and lenders need to satisfy themselves that practically all of their borrowers will be able to repay. There is everything to recommend a business borrowing to expand where there is a profitable market to serve. There is nothing wrong with an individual borrowing to buy a home or a decent car if they have reasonable prospects of continuing employment with future pay rises.

The manufacturing fall probably means Germany is  now in overall recession, given the salience of manufacture and the car industry to her economy. China is still growing, but as the world’s major manufacturer it too has been slowed by recent trends.
