In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
Bothe the Khutbas of Juma should be delivered in Arabic. it is sunnah. Delivering Khutba in other than Arabic language is against sunnah and makrooh. From the time of Sahaba it has been always in Arabic. If the Imam wants to inform people about Islam and its do’s and don’t’s, he should deliver speech in regional language, then give a short break to offer 4 rakat sunnah, after that the 2 khutbas of Juma he should deliver in Arabic only.
