Inflation figures are out at 9:30am. The consumer price index (CPI) is expected to remain at the current level of 2.4% as is the retail price index (RPI) at 2.8% in England.
The latter will be watched very closely today since the RPI figure will be used to set future rail ticket prices. Read more on how this is calculated here.
Tens of thousands of rail commuters will have to pay more than £5,000 a year for their season tickets after new rises come into effect in January, the Transport Salaried Staffs Association (TSSA) union warned today.
The TSSA made the claim as it joined other unions, transport campaigners and rail passenger groups in a day of action to protest at fare increases and cuts to jobs and services.
The environmental group Climate Rush has tweeted these photos of its protest against a planned hike in rail fares outside Waterloo station.
In one photo, demonstrators recreate an infamous photo of the Prime Minister and London mayor Boris Johnson posing as members of the Bullingdon Club - an exclusive gentleman's club at Oxford University. The Chancellor George Osborne was also a member of the club in the 1990s.
The transport minister Theresa Villiers has said that more funding is needed for Britain's railway network in order to make it run more smoothly and cheaply.
She told ITV Daybreak that a "huge programme of rail improvements" is underway and that the Government is investing in the network, but that passangers also had to shoulder some of the costs.
Referring to the 20,000 jobs that could be at risk, she said that only these sorts of "efficiency savings" would "relieve pressure on taxpayer".
The transport minister Theresa Villiers has told Daybreak that rail fare increases are 'making a real contribution to a huge programme of rail improvements'.
Campaigners have said commuters to London were routinely spending up to 15% of their salary on getting to work.
By 2015, this will create a series of "£1,000 towns" - places where commuters will see the cost of their annual season ticket rise by more than £1,000 between 2011 and 2015.
The transport secretary Justine Greening has said she is keen to see "what we can do to keep rail fares down to something affordable".
She added: "I shall be looking at whether there is a way of doing that in the autumn but we have to stick with our deficit-reduction policy."
Ms Greening was asked whether there would be Treasury money available for rail that would enable the fare rise to be reduced. She replied: "Well, if you don't ask, you don't get."

The case for re-nationalising our railways, and throwing the extortionists and rip-off merchants off the tracks, is now overwhelming.
The public is sick and tired of being charged through the nose to travel on creaking, overcrowded trains while the rail companies are robbing them blind.
