I'm guessing there's a battle royal going on in Whitehall atm in relation to the Chancellor's Spring Statement. Treasury line will be "you had your big increase in 2020 so sod off" and their fallback position may be a one-off extra amount this year that doesn't further hike the Mod's baseline. The counter argument will point to the changed set of circumstances we now face plus all the big increases elsewhere in Europe (most notably Germany) and pointing out that the UK needs to follow suit if it wants to maintain its position as a leading European power.
And of course most of the last increase was swallowed up by the black hole. We have to hope that if there ARE any increases announced in the near future, they are clearly badged to specific measures/acquisitions, ie it needs to be very clear what any extra is actually going to provide.
