Prepositions with abbreviations

“Of MP”, “in MP” or “for MP” ?

The abbreviation “MP” usually means “Member of Parliament.” “For an MP” is common when something is intended for or supporting a politician. “Of an MP” appears in longer phrases showing possession or connection. “In MP” is not a standard combination except in special contexts.

Quick answer

Which form sounds natural?

Use “for an MP” when something is intended for, supporting, or connected to a Member of Parliament. Use “of an MP” after another noun, such as “the duties of an MP.” “In MP” is generally not idiomatic unless “MP” refers to a different abbreviation or functions as part of a separate phrase.
