Osborne 'is set to scrap fuel duty in the Budget' to help with the cost of living Cameron said he and Coalition will do 'everything we can' to help drivers Next week's Budget is set to include a raft of measures to ease cost of living Osborne is expected to expand a help for first-time house buyers Supporting drivers: George Osborne is set to announce scrapping fuel duty as well as offering a generous childcare tax break A fuel duty rise scheduled for the autumn will be scrapped in next week's Budget, according to Government sources. It comes after David Cameron said he and the Chancellor would do "everything we can" to help drivers struggling with the cost of petrol. It means the Coalition has scrapped or frozen every scheduled fuel duty rise since 2010. Another potential boost for families will be the long-awaited announcement of the Coalition's childcare tax break, which will be more generous than expected. Parents earning up to £150,000 are expected to benefit from tax relief which could be worth £1,000 or more, to help with the soaring costs of childcare which is hurting middle and working class families. The Government believes a million women who want to work are missing from the workforce, put off by high fees for nurseries or childminders which are among the most expensive in Europe. Both measures are revealed in today's Spectator magazine. Fuel duty will be the centrepiece of a raft of measures to help with the cost of living that will be announced in next Wednesday's Budget. The Prime Minister, who was tackled on the issue while visiting the Mercedes-Benz plant in Milton Keynes this week, said: "I totally understand that many people have to run a car. It's not a choice, particularly if you live in rural areas. I understand that people look at the price of petrol and diesel, they look at the cost of running even an inexpensive family car and it's still a very big amount they are paying. Prime Minister's pledge: David Cameron said that he and the Coalition would do 'everything we can' to help drivers at the Mercedes-Benz plant in Milton Keynes last week So we've got to do everything we can to help people get on, help people get to work, help people live their lives. It comes after George Osborne announced in December he would scrap a planned 3p hike in fuel duty set for January and postpone a rise set for next month. While the Treasury say petrol is now 13p lower than it would have been under Labour, figures from the RAC Foundation show that 800,000 British families now spend one quarter of their income on running a car. Two thirds of the pump price is tax. In another measure, families who want to upsize are to be offered government help to buy their second home with a five per cent deposit. Mr Osborne is expected to expand a scheme currently aimed at first-time buyers to help so-called "second-steppers" in a new attempt to revive the stagnant housing market. High petrol prices: David Cameron said last week that even running an 'inexpensive family car' still costs a 'very big amount' The NewBuy scheme, which sees the government and banks underwrite mortgages, allows first-time buyers to purchase a property with only a five per cent deposit. The scheme has so far helped 1,522 first-time buyers get their foot on the property ladder, and will now be offered to second home buyers. The average age of a first-time buyer who does not get help from family is now 33, but that rises to 41 for those buying their second home. Fresh support is also likely to be targeted at the under-30s after Mr Cameron renewed his commitment to a "property-owning democracy" last month. He said: "We don't want to go back to the days of 110 per cent mortgages and encouraging people to take on borrowing that they can't afford. But it is important that people who work hard and do the right thing are able to buy a home. It is a rebuke to those of us who believe in a property owning democracy that the average age for someone buying their first home today, without any help from their parents is 33 years old.
