President Uhuru Kenyatta and his deputy, William Ruto spent Sh666.9 million on their entertainment expenditure.
According to data from the Controller of Budget, the figures were nearly doubled six months to December when the country experienced a prolonged election period.
The amount went up from Sh360 million in a similar period a year earlier, according to the Controller of Budget report.
The 85 percent rise in spending on hospitality, includes drinks and catering, came in a period when the two were campaigning for office.
The prolonged election period started ahead of the August 8 General election and continued to the end of November when Mr Kenyatta was declared the winner after the repeat October 26 presidential vote.
The Supreme Court nullified the August 9 poll over irregularities, triggering another round of political campaigns.Besides the Presidency, the only ministry that spent more than Sh100 million on hospitality is Foreign Affairs at Sh246.3 million.
The Treasury has in the past four years struggled to implement austerity measures prompted by underperformance in revenue collection amid rising expenditure.
