The reason why she was not able to marry Peter Townsend was because he was divorced.
There was a piece of fluff on the lapel of Group Captain Peter Townsend. Princess Margaret removed it.
Short answer? NOTHING!! They were never married, nor even engaged, since Princess Margaret (for whatever reasons: personal or Constitutional) refused his offer. Princess Margaret married Anthony Armstrong-Jones, Earl of Snowdon, in 1960. That was her only marriage.
She didn't forbid Margaret to marry, she only asked her to wait one year before deciding to marry. Margaret was in love with Peter Townsend, a commoner, who was divorced, which was not allowed by the Church of England. Margaret waited and ended up marrying Antony Armstrong-Jones and having 2 children. They divorced in 1978.
