Although the Met has said

"Although the Met has said there is no specific threat to the festival, the 2017 parade, expected to be attended by tens of thousands of people, will be protected by armed officers, and marchers will be shielded from traffic by concrete bollards." (The Guardian.)

the 2017 parade - a subject;

will be protected - a predicator;

marchers - a subject;

will be shielded - a predicator.

There are two independent clauses linked by the conjunction "and" and the subordinate one introduced by the conjunction "Although" in the above. There is also a non-finite 'ed' clause there (in apposition to the clause subject) functioning as an adjunct. The subordinate clause has "the Met" as a subject, "has said" as a predicator, and 'that' clause as a direct object.

Am I right?
