The fervour has been building up in the UK around Modi's three-day visit starting Thursday, which will include a grand reception at Wembley Stadium described as the "biggest political rally in the history of the UK" on Friday.
"Since he swept to power 18 months ago, Indian Prime Minister Narendra Modi has proved to be a charismatic international statesman, impressing leaders from Shinzo Abe to Barack Obama as well as expatriate Indians with his ambition to modernise India," The Financial Times' said.
The newspaper, however, stressed that the UK will be keen to distance itself from any negatives to clinch an estimated package of USD 15-billion trade and investment deals.
'The Independent' newspaper also feels the drubbing in the Bihar elections is an "embarrassing setback" coming on the eve of the high-profile visit.

"The result means that as he prepares for an enthusiastic welcome in Britain this week - including an unprecedented sell-out event at Wembley Stadium on Friday - Mr Modi will be smarting from the defeat on home soil, which comes as his administration also faces mounting accusations of fomenting intolerance," the newspaper said.
"As he emerged from provincial politician to likely leader of the world's largest democracy, Britain ended the boycott in 2012 in the face of growing business and realpolitik pressures.
"The turnaround has been dramatic. This week he will stay at Mr Cameron's country residence (Chequers), address the two Houses of Parliament, visit Indian-owned businesses and sites of Indian cultural importance," the daily said.
The news reports come against a backdrop of the so-called "Modi Not Welcome to the UK" protest group projecting a hologram with its banner on the House of Parliament on Sunday night. The group led by Awaaz Network is among some of the UK-based organisations planning protests during the visit this week.
