The Chamber was not so full for Boris Johnson and Sir Keir Starmer as it had been the previous day for the Ukrainian President, Volodymyr Zelensky.

One cannot say that our legislators’ order of priorities was wrong. Zelensky talked with deep emotion from Kyiv about a war for national survival. Sir Keir talked with no great emotion from Westminster about energy prices.

He said the typical household energy bill will rise by £700 next month, called for a windfall tax on the oil companies’ profits and asked when the Prime Minister will “force the Chancellor into a U-turn”.

“I think that he’s absolutely out of his mind,” Johnson replied, and accused the Leader of the Opposition of wanting to get rid of £20 billion of support for households already announced by the Chancellor.

The Prime Minister proceeded to mock Sir Keir for a Labour U-turn. He said he was “overjoyed” that Labour now supports the building of new nuclear power stations.

“Twelve years in power and that’s the best he can do?” Sir Keir retorted, but somehow the retort lacked bite, partly because it was impossible to imagine that Labour would have built any nuclear power stations in those years.

Rachel Reeves, the Shadow Chancellor, sat nodding and smiling beside Sir Keir. Nobody could have looked more loyal, yet there was also something chirpy about her.

Was Reeves contemplating how she might have managed to give Johnson a harder time? That is an easy thing to dream about if one does not actually have to do it.

Ian Blackford, for the SNP, chose the subject Sir Keir had avoided: the strikingly small number of Ukrainian refugees admitted by Britain.

So did Sir Ed Davey, for the Liberal Democrats, Julian Smith, from the Conservative benches, and quite a few Opposition backbenchers.

“The Prime Minister, the Deputy Prime Minister, the Home Secretary are directly descended from refugees,” Johnson told Blackford.

How then could they be anti-refugee? Look at the numbers admitted from Afghanistan and from Hong Kong.

“No one has been turned away,” Johnson told Sir Ed. Yet MPs told of various Ukrainian refugees who had at the very least found themselves confronted by bureaucratic hurdles which are extremely difficult to surmount and inflict long delays.

Johnson said the numbers of Ukrainians admitted will quickly rise. He sounded in command of the situation, and he was certainly in command of the Chamber. Whether this lasts we shall see.
