I don't want to know what I should or shouldn't do

Nor does Raab.

Apparently the government advice is you can meet one person. Rabb was asked on the radio if that meant you could meet both parents (assuming social distancing)

Yes, says Raab that's ok.

Immediately the government spokesman clarifies, that you can see both, but not at the same time.

This proves
(1) The message is so confusing even the guy you chose to do almost every daily press conference can't understand it.

(2) The government spokesmen doesn't understand that it does almost nothing whatever to your parents' risk of infection if you see them together for 30 minutes, or one after the other for 30 minutes each even with a gap of a day or two (though the latter might increase your risk if you are out more).
