The sun shone, and shone! Temperatures breached 30 degrees in some parts of the country. Meanwhile, the inconvenience caused by the NHS app continued to cause chaos, with half a million people having to isolate despite the fact they were not ill. The situation was not helped when business minister Paul Scully said he would encourage people who are "pinged" to self-isolate, but they could make an "informed decision". He was then slapped down by the Government. The app has always been voluntary to download and any alerts advisory. My first commitment was to attend a virtual meeting of the Covid Recovery Group. I think it fair to say that no one was happy with the situation surrounding this NHS app. Next up was a bruising session of our Defence Select Committee. I say bruising because we took oral evidence from the makers of our new, lightweight tank, the Ajax, which is not going well. There were two panels. Carew Wilks, Vice President & General Manager at General Dynamics Land Systems UK, and Scott Milne, Executive Programme Director at the same company, were the first two witnesses. The second panel consisted of: Jeremy Quin MP, Minister for Defence Procurement; David Williams CB, permanent secretary, MOD; Lt Gen Ralph Wooddisse CBE, MC, Commander Field Army, MOD; and Maj Gen Timothy Hodgetts CBE, Surgeon General, MOD. The questions came thick and fast and the answers frequently failed to satisfy my colleagues. What is alarming is that this multi-billion project might have to be scrapped due to a series of faults. We put a spotlight on yet another defence procurement project that was going seriously wrong. The taxpayer is of course the loser, so, too, are our soldiers, who would need this light tank in a future conflict. Later, I joined another virtual meeting with a small group of my colleagues for the last time before the summer recess. In other news, France would double the number of police patrolling its beaches as part of a deal with the UK to stem the number of migrants crossing the English Channel. The UK would pay more than £54 million as part of the deal agreed between ministers in London and Paris. The Home Office said the two countries would also improve intelligence sharing and use better technology to target those who organise the crossings. Yesterday, at least 430 migrants crossed the Channel - a record for one day. Finally, Dominic Cummings emerged from the shadows again in his bid to further smear the PM. I find the whole thing quite appalling. You were sacked, Mr Cummings, get over it.
