MOSCOW, June 30 (Reuters) - The Kremlin said on Thursday it has not yet decided whether President Vladimir Putin will attend November's G20 summit in Indonesia.

In a call with reporters, Kremlin spokesperson Dmitry Peskov said Russia had an invitation to attend and would decide "at the necessary time" whether Putin will go in person.

Western leaders are weighing up how to approach the summit should Putin go, with British Prime Minister Boris Johnson calling on leaders not to boycott if the Russian president does decide to attend. (Reporting by Reuters)
