IT is billed as an “inter-governmental political forum” – a high-powered talking shop – where the leaders of the world’s richest democracies gather to discuss or work out how to resolve global problems such as Covid-19, climate change, economic crises and, of course, Brexit.

Organising such summit is a massive logistical exercise, but it operates on a rotating presidency and we have been here before – the first G8, as it was then, in Scotland was at Gleneagles in 2005, and others have been held in London and Birmingham.

This weekend may be the first time the G7 has been held in Cornwall, the normally sleepy, south-western corner of England, but the problems are familiar.

Devon and Cornwall Police force has around 1500 officers, but 5000 others have been drafted in to support them, with 1000 billeted in a ship moored in Falmouth.

This is the first time the leaders have met in nearly two years because of the pandemic, and the fight against Covid-19 is one of the main items on the agenda, along with climate change.

Boris Johnson has already been slated for using a private jet to travel the 280 miles from London to Cornwall, and protesters have promised to come out in force. Extinction Rebellion activists have travelled from Scotland to Cornwall, and a spokesperson from Glasgow said: “Decisions made at the G7 summit this weekend will set the agenda for the COP26 conference in Glasgow in November, so we want to make sure that the world leaders know that we are watching them closely.”

Of course there is Brexit, and the UK-EU row over the Northern Ireland Protocol. This is Joe Biden’s first overseas visit as US president, and his national security adviser Jake Sullivan has warned: “President Biden believes and has said that the Northern Ireland Protocol, as part of the agreement between the UK and the European Union, is critical to ensuring that the spirit, promise and future of the Good Friday Agreement is protected.”
