Defra minister George Eustice will appear before MPs to give details on the progress of payments made to farmers under the new Common Agricultural Policy system.
The Environment, Food and Rural Affairs Committee will be holding an evidence session on Wednesday which will focus on the government's views on how the programme is to be taken forward.
The Rural Payments Agency (RPA) started contacting farmers who have not yet received their 2015 BPS payment to provide greater clarity on when they will be paid.
Farmers will receive an email (or letter if they don’t have an email address registered in the Rural Payments service) during March and the RPA aim to have contacted everyone by the end of this month.
Around 15,000 farmers are still waiting for their payment in England, while 72,700 farmers have already received theirs.
The total being paid out for the 2015 remains at £1.15 billion.
"Looking at the payment performance in February where, as far as we can tell, a very disappointingly low number of 4,900 were paid then the sooth-sayer in me is starting to question the RPAs prediction that they will get 95% paid by the end of March (that is considered to be ‘almost all’ in their mind)," said NFU vice-president Guy Smith.
"And we should not forget even if this target is hit it will leave close to 5,000 unpaid who will have been waiting without payment for over 120 days since the payment window opened. It’s hard to believe the RPA have good cause or reason to keep this many waiting this long."
A number of claimants have discovered that their 2015 payment has been lower than expected and with most claim statements still to arrive it has been difficult to identify why this might be the case.
Paul Dennison, farming consultant in Strutt & Parker’s Northallerton office said: "One was a client who received a claim statement which showed an over-declaration of 45ha so the client has been penalised for double the over-claimed amount which equates to more than £15,000.
“However, when I checked the online system one field on the claim, which historically had an eligible area of 43ha, now has an eligible area of 0.00ha, which is suspiciously similar to what the RPA has said is the over-claimed area.
“It does appear that in some instances the system may have got things wrong so now is the time for people to double-check their figures and seek help if they need further guidance on how to contact the RPA to get land reinstated.”
