Fifty percent plus one only applies to an even number of members in the parliament. Whenever you have an odd number of members ( 53 , 65 ), the majority is 33 to 32. It has been this way since 2011 and all budgets and legislation were passed with a 33 majority. There is no half person in parliament when I last checked. The constitution never mentioned anything about 34.
Let the campaign start. The people will decide using their democratic right.
