LONDON, Sept 22 (Reuters) - The British government has plans in place to bring home stranded holidaymakers if Thomas Cook goes out of business, an event that would likely spark chaotic scenes at resorts and airports around the world.

The bosses of the world's oldest travel company were still meeting lenders and creditors in London on Sunday to try to thrash out a last-ditch deal to keep the company afloat.

The company's board will then meet in the early evening to decide the company's fate, with the business potentially going into administration in the early hours of Monday.

Running hotels, resorts and airlines, Thomas Cook has 600,000 customers on holiday, meaning governments and insurance companies could be forced to step in and bring them home if the company goes out of business.

Unions and the opposition Labour party have urged the government to stump up the cash, but the foreign secretary appeared to dismiss that idea on Sunday.

"We don't systematically step in with the taxpayers' money when businesses are going under unless there's a good strategic national interest," Dominic Raab told the BBC, adding that plans were in place to prevent anyone from being stranded.

The company, founded in 1841, has been fighting for its survival after its lenders threatened to pull the plug on a rescue deal that has been months in the making.

Hurt by high levels of debt, online competition and geopolitical uncertainty, Thomas Cook needs to find another 200 million pounds on top of a 900 million pound package it had already agreed, to see it through the winter months when it has less cash coming in and needs to pay hotels for summer services.

That has sparked fears among customers on social media that some hotels, yet to be reimbursed by Thomas Cook, could ask holidaymakers to leave if the company collapses.

Some British tourists were briefly detained in a hotel in Tunisia by staff who wanted to know if they had been paid. The Thomas cook customers have since left and flown home, according to their social media postings.

At the meeting on Sunday the company was asking its lenders to restructure or lower their demands. It has also asked credit card companies to release 50 million pounds that they hold as collateral against the company's bookings.

The company's largest shareholder, China's Fosun, was due to take a central role in the restructuring.
