Last Saturday the leaders of the UK, France, Poland and Germany visited Kyiv to put on a show of support for Ukraine President Volodymyr Zelensky.

A deal on food and drink checks would deliver very little, he believes, because food and drink is such a limited part of trade. "If you were, for example, aligning UK and EU rules on industrial products, you'd get a much bigger economic impact".Jill Rutter thinks that a veterinary deal would not prove "economically earth shattering" – but if it goes well, she argues that it could provide "early proof of concept" for further UK-EU cooperation.

After Brexit, many British fishermen were disappointed when Boris Johnson's government agreed to let EU boats continue much as before, taking significant catches from UK waters. Those arrangements expire next year. The EU wants them extended.David Davis who, as Brexit minister, led some of the original negotiations for the UK, told me fishing was "totemic" for Brussels. London conceded too easily, he thinks."Europeans got what they wanted first, and then we had a haggle from a weak position."

So he adds, "If I was giving advice to the government, I would say, tough it out" and use fishing as a lever to seek concessions.But, as the UK found before, Brussels has cards to play. Much of the fish caught by British fishermen is sold to buyers on the Continent and the UK needs access to that market.

Some EU coastal states, like France and Denmark, are prepared to drive a hard bargain, demanding that London concedes on fishing rights in return for things it wants. Early on, even signing the Security Partnership was being linked to agreement on a fishing deal. The haggling will be tough.

And finally, there's an idea that has prompted much interest in recent months: a youth mobility deal, through which under-30s from the UK and EU could live and work in each other's countries.Taiwan was on high alert for possible threats from China on the day the men were apprehended: the one-year anniversary of the inauguration of Taiwanese president William Lai, whom Beijing reviles.

Last week a Chinese father and his teenage son landed in Taoyuan on the northern tip of Taiwan's main island, after crossing over in a small rubber dinghy.Questions were raised about how they managed to travel more than 100km across the Taiwan Strait - one of the most heavily patrolled patches in the region and a busy international shipping lane - without being discovered.

The coastguard confirmed the landing occurred on 16 May, but admitted that they had not detected the boat before it landed as it was too small to be picked up on their radar technology.The father and son, who were from the southern Chinese province of Fujian, reportedly claimed they were victims of persecution in China and wanted to "seek freedom" in Taiwan.
