New Delhi: Injecting a note of levity in his somber budget presentation, a smiling Finance Minister Pranab Mukherjee told the Lok Sabha on Friday that he had no problem in a "rollback of the speech".

Mukherjee, who had to interrupt his reading of the budget because some members of the house could not hear it properly, offered to read some paras again. "Rollback of the speech, no problem," Mukherjee said, smiling broadly, as the house interrupted in laughter.

The reference was, of course, to the rail budget where United Progressive Alliance (UPA) ally Trinamool Congress has asked for a rollback of the hike in passenger tariff.
