Santander said on Friday it was offering Banco Santander Mexico's minority shareholders 26.5 Mexican pesos ($1.30) per share, up from 24 Mexican pesos previously.

The offer, which the lender expects to launch on November 3, would be worth more than 600 million euros ($700 million).

Santander has expanded in emerging economies where it hopes to register a faster growth than in Spain and Britain, its core markets in Europe.
