Holiday firm Thomas Cook is expected to see profits fall when it posts its annual results on Wednesday, buffeted by terrorist attacks in Tunisia, Egypt and Paris.

The City expects it to report underlying earnings down 5% to £307 million, as rising summer bookings were offset by growing geopolitical tension.

Analysts at Jefferies add that the closing of the airport at Sharm el-Sheikh in Egypt after the downing of a Russian passenger carrier last month will cost the 174-year-old travel firm £5 million.

The Tunisian beach and hotel attacks in June will cost it another £5 million, according to the broker.

The Paris street attacks this month will fall outside of the firm's reporting period, but investors will want to know the effect this having on current trading from chief executive Peter Fankhauser.

Mr Fankhauser succeeded former boss Harriet Green in a surprise announcement a year ago.

Ms Green inherited a business in 2012 that was on the brink of collapse, and cut costs and purged low-margin operations to restore the firm.

But critics of Ms Green, who was recruited from Leeds-based technology distributor Premier Farnell, said she did not understand the travel business well enough to grow the group.

In a September trading update, the group's holidays were 95% sold for the summer season in Britain, 1% ahead of the same period in 2014, as the UK ''continues to perform comfortably ahead of last year''.

However, average selling prices were 1% lower, due to an increase in the proportion of ''seat only'' sales rather than packages.

Thomas Cook signed a joint venture agreement in June with Shanghai-based conglomerate Fosun, in a bid to cash in on China's £85 billion tourist market.

The deal will see domestic, inbound and outbound holidays sold in China through a business that will be 51% owned by Fosun, with the rest owned by Thomas Cook.

However, the Chinese market has slowed since the summer and brokers say there has been little evidence of the partnership.

Jefferies said: "Thomas Cook is transitioning to higher quality growth, just more slowly than we initially envisaged."

Earlier this month, a report found Thomas Cook prioritised cost cutting over customers and still needs to address safety issues nine years after two children died from carbon monoxide poisoning at a hotel booked through the travel company.

Bobby and Christi Shepherd, aged six and seven, died in 2006 as a result of a faulty boiler at a bungalow attached to the Louis Corcyra Beach hotel on Corfu.

Thomas Cook was slow to respond to their deaths and was insensitive in its dealings with their parents, said the report commissioned by Thomas Cook and overseen by former Sainsbury's boss Justin King.

The new boss at All Bar One and Harvester owner Mitchells & Butlers is expected to post a rise in annual profit on Tuesday.

The City expects the Birmingham-based pub group to lift full-year pre-tax profit by 10.8% to £190.7 million, after it earlier posted a 1% like-for-like sales rise for the first 50 weeks of the year.

Investors will get a good look at new chief executive Phil Urban, who replaced Alistair Darby in September after a washout summer prompted it to warn over profits.

The business, which owns more than 1,800 pubs, said like-for-like sales fell to 0.7% in the seven weeks to September 12 after a wet summer led to slowdown in growth.

Mr Urban, joined the company as chief operating officer in January from Grosvenor Casinos, and previously ran Whitbread's pub restaurants division.

Mr Darby left the business after three years in the role, having been appointed chief executive in October 2012.

Analysts at Goodbody said they will look for more positive sales over recent weeks aided by the Rugby World Cup and the high proportion of the group's estate based in London.

Investors will want to know how Mr Urban will manage the introduction of the living wage after Chancellor George Osborne said in July he would raise the country's hourly minimum wage from April next year to £7.20 for over 25s, from its current level of £6.50, and to at least £9 an hour by 2020.

However, the business is in good shape ahead the introduction of Government legislation next June that allows tenanted pub landlords to break the link with their pub group, leaving them free them to search for more competitive beer contracts.

The vast majority of the group's pubs are managed and owned by the chain, which means unlike rival firms, it will have little to do to prepare for the change.

Last June, Mitchells & Butlers bought rival group Orchid's 173-pub estate for £266 million.

At its September update, the group said it opened 14 new pubs and converted 48 sites, including 38 Orchid outlets into Mitchells & Butlers brands such as Toby Carvery, Ember Inns, Miller & Carter and Harvester.

Two for One and Pitcher & Piano owner Marston's is expected to report higher full-year sales on Thursday as it continues to build larger pubs that serve food and cater for families.

The City forecasts the Wolverhampton-based firm, which operates 1,600 pubs, will post annual pre-tax profits up 10% to £91.5 million, after opening 25 new pub restaurants last year.

The firm added in a full-year update last month that like-for-like sales at its premium pubs lifted 1.8% compared to 12 months ago, while like-for-like food revenues lifted 1.7% over the same period.

The business - which also brews Bank's, Marston's and Ringwood - said its beer brands performed well rising 5% compared to the same period year ago.

It plans to build another 20 premium pubs next year, adding it has largely competed its sell-off of pubs that cannot comfortably be converted to serve food.

Chief executive Ralph Findlay said: "The group has made good progress in the last year, with underlying growth in all of the business segments.

"Our new pub-restaurants, premium pubs and lodges have all performed well and we have good visibility over the site pipeline to underpin our future growth."

Earlier this month, the country's largest pub group, Enterprise Inns, posted flat annual profits today as it sells off hundreds of sites in preparation for the end tied pubs.

The Solihull-based firm sold off 260 pubs for £75 million in the year, as it prepares for new legislation that allows tenanted pub landlords to break the link with their pub group, leaving them free them to search for more competitive beer contracts.

Enterprise Inns, which has around 5,000 outlets, said its pre-tax profits before exceptional items edged up 0.8% to £122 million in the year to the end of September compared to 12 months ago, citing lower interest charges.
