In vs to

[Jignesh]

It came as the EU said it would back a short delay to Brexit- if MPs finally vote in favour of Theresa May's deal next week.
I read the above in The Metro newspaper.

Please explain the use of the preposition "to" in "delay to Brexit".

Would the preposition "in" be equally correct "delay in Brexit"?

I am really confused as there are multiple definitions in the dictionaries for both these prepositions. I have checked the Coca corpus and it states "in" is the most common preposition followed by "delay".

"To" is used generally when or where some direction is involved

Both are possible in this context.
