Up to London, with sobering news from Scotland. There, more than two million people will be placed under Scotland's toughest Covid lockdown restrictions from Friday. The move will see level four rules imposed in 11 council areas across western and central Scotland, including Glasgow. It will mean non-essential shops, pubs, restaurants and gyms will have to close, although schools will still be open. The level four restrictions will remain in place until 11 December. Sturgeon is certainly generous with her tiers! Spent some time preparing for another public session of our Defence Select Committee at 1400. Today, we continued to look at our defence industrial policy, procurement and prosperity. We had four contributors: Jeremy Quin MP, Minister for Defence Procurement, Air Marshall Richard Knighton, Damian Parmenter, Director, Defence & Security Industrial Strategy and Huw Walters, Director, Economic Security & Prosperity. The revealing session lasted more than two hours and can be found on Hansard. One surprising element were questions I put to the team on the failed procurement process for the Fleet Solid Support Ships, whose role will be to sail with and support our two, new carriers. We learnt that tenders were going out again in the spring and no date could be given when a ship would be commissioned. Not good. At 1600, I joined the first of two private virtual meetings with colleagues, both lasting an hour. It meant there was no time to speak in the debate on the National Security & Investment Bill, although we are covering this ground in our defence committee. Packed up at 1900 and headed home. In other news, Labour has - mistakenly, in my view - readmitted former leader Jeremy Corbyn as a member following his suspension last month. He was punished after saying the scale of anti-Semitism in the party had been "overstated", in response to a damning report by the Equalities and Human Rights Commission. Mr Corbyn issued a statement earlier saying he regretted any "pain" caused. But current leader Sir Keir Starmer maintained that Mr Corbyn's initial reaction to the report had been "wrong". This news is not going to go down well with many decent Labour MPs, or with the public. It makes Starmer look very weak. On our side of the House, our Scottish leader Douglas Ross was dealing with the fallout from the PM's comment that devolution under Blair was a "disaster". Mr Ross claimed that the PM had meant it was the SNP's "obsession" with independence, rather than devolution, that was the problem. Not surprisingly, the SNP did not look at a gift-horse in the mouth and immediately countered that this proved the PM's "contempt" for Scotland. Of course, it did nothing of the kind. The remark was aimed at a disingenuous and destructive SNP, who would willingly lead the Scottish people over a cliff to economic Armageddon.
