UBS's UBSG.S multi-billion state-sponsored takeover of Credit Suisse CSGN.S should proceed smoothly without political obstructions, Swiss Finance Minister Karin Keller-Sutter said in an interview published on Saturday.

The Swiss parliament is due to hold an extraordinary session next week to discuss the emergency merger engineered by the Swiss authorities after Credit Suisse came close to collapse.

Nearly 260 billion Swiss francs ($287 billion) of liquidity support and state guarantees have been offered to back the takeover and avoid a financial meltdown the bank's uncontrolled failure could have triggered.
