If you pick the right solicitor it will make a great deal of difference, in my view.
The right solicitor will be known at the court, be experienced in your type of alleged offence and guide you through and assist with your plea, defence, or mitigation. As stated earlier you may find you are eligible for legal aid and I have given you the contact telephone number.
The only problem may be that legal aid is so poorly paid not all solicitors will work at these rates, but there are many good solicitors who will and they can make all the difference.
