In my own words: "For the first time we are in a position to take on the responsibility of power. After more than 70 years of campaigning as a party, we are now ready to play a part in the government of our country."
"Wales cannot afford to have its assembly run by those who were, at best, half-hearted about its existence. It must be determined primarily by the needs of Wales and by those who give their first allegiance to Wales."
Labour would "run the assembly as if it were a branch office of Millbank [party press office]".
"It is not Plaid Cymru's objective to see ourselves as a small opposition group within the assembly. The objective of Plaid Cymru is to form a government of Wales. If Plaid Cymru is the largest party in the assembly we shall form a government."
How others see him: The voice of Welsh nationalism in the Commons for nearly 25 years. Reasonable and friendly though was once so angry about a procedural point that he banged the arm of the Speaker's chair and broke it off.
Works hard for the disabled, spastics, mentally handicapped and the blind, sponsoring the Disabled Persons Act in 1981. Two of his sons died of a rare genetic disease - has taken a strong view on the importance of embryo research.
