* It wasn't the general election.

* They offered local councils the chance to request it if they were going through a reorganisation or devolution process.

* 18 councils requested and 9 were accepted as justified.

* And even those are only delayed until May next year (one year after the rest of the UK).

So to be clear the UK government not only didn't postpone the general elections but half the councils who requested the local elections were postponed were denied, with the other half having reasons and still doing it a year later anyway.

And all that is actually covered in the page you link to.

Your link points to _some_ local council elections (the people responsible for bin collections, parks and care homes) and the extension has been requested by the local councils themselves.
