are you a time traveler from before the 1640s?
there was a civil war fought over this point, parliament won and is sovereign
the parliamentary majority and government are not the same thing
this should be obvious to anyone from the 2019-2020 mess where the government didn't have a majority
there is no government approval anywhere in the legislative process
most bills are proposed by government ministers (by the fact they also happen to be parliamentarians), but this is also not a requirement
bills can be proposed and passed into law entirely by parliament, they're called "private members bills"
