The Eknath Shinde and Uddhav Thackeray-led factions of the Shiv Sena will celebrate the party`s foundation day at separate events in Mumbai on Monday, reported news agency PTI.

Bal Thackeray, a political cartoonist, founded the Shiv Sena on June 19, 1966, and made the pride of `Marathi manoos` (Marathi speakers in Mumbai) the core plank of its politics.
