Why do you have data with leading spaces in the tables? Why have you not cleaned that data and removed the leading spaces? (and yes, you will need an LTRIM and hence a poorly performing query to do what you want)

You are correct, the data should be clean. But sometimes we have no control on the data and it is provided by third party. All we can do is some defensive programming.

The third party inserted it into your database and you don't have rights to run updates?

In this case, defensive programming = slow queries. If your users are happy to have things running slower than they could, then fine.

Its not that simple.
The third party provides data, another team loads the data and we use the data to display on front end.
The team that loads the data will need to clean the data, but they do not want to do it and we do not have rights to update the data.

L TRIM removes all the white space from the starting of the pattern and R TRIM removes all the white space at the end of the pattern.:-)

Sorry, but that's factually incorrect for SQL Server. For SQL, LTRIM and RTRIM affect only spaces, not all whitespace characters.

Wow. I really feel for you there. I have to stop there because nothing civil would come out of my mouth about such a "team".

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair
