As a Southend fan I sympathise with your situation, we face a winding up order on the 18th, it’s close to our 20th winding up order, (still unbeaten vs HMRC), as long as the HMRC have a reasonable expectation to get paid in full they will adjourn.
If however they have no realistic expectation to recover the debt they may be more aggressive.
This winding up order will put you under an embargo in this league, hopefully your takeover can go through and you can clear the debt.
