In response to criticism from Matthew Oakeshott*, Kirsty Williams, leader of the Welsh Liberal Democrats, has told BBC-Wales:
"Nick has had the courage of his convictions during this election campaign to make a positive case for what the Liberal Democrats and the Welsh Liberal Democrats believe in.
"I cannot be any clearer.
"I think Nick Clegg is the right person to lead this party into the general election and what we need to do now is re-double our efforts and explain to the people of this country why we took the decision to be in coalition government and what the Liberal Democrats are achieving as part of that government."
*Oakeshott is the former self-appointed treasury spokesman for the Liberal Democrats in the House of Lords who has now left the party.
