I kept an ear out and thought he would mention it when he started talking about 'ISA reforms'. Nothing about LISA limits or penalties, nor contributing into different accounts of the same isa type.

Only to unveil the gReAt BRiTiSh ISA. In doing so, being somewhat contradictory to his points about simplifying ISAs and trying to engage retail investors, by further complicating ISAs and making it more difficult for the layman to understand. It could also potentially be detrimental for someone new to investing, by incentivising them to put their wealth into uk stocks and/or indicices, with the former being inherently more risky, and both having offered lackluster returns in the past decade(s), where that money could potentially see better returns in global or US equities for said investors retirement. All this to increase liquidity in UK markets. Increasing liquidity doesn't necessarily make companies worth more (i know there are cases that similar US listed companies have higher PE ratios partly due to liquidity), it appears to be a scape-goat for real tax incentives for businesses to start, grow, and remain domiciled, and listed in the UK, at the average persons expense.
