The leader of the Liberal Democrats in Wales, Kirsty Williams, has resigned.

It follows a disastrous night for the party, before the Assembly Elections there were five Lib Dem AMs, this morning there was only one, herself.

The loss of four Assembly Members means Kirsty Williams will be the only Lib Dem in the Senedd.

Williams successfully defended her Brecon and Radnorshire seat at this morning's count.

She won 52% of the vote - increasing her share by almost 10%.

But that was not reflected elsewhere in Wales as UKIP swept up seven seats for the first time.

Despite our best efforts, and a positive campaign, it has not been enough. And for that, I must take responsibility. In these new circumstances, the party will want to reflect and consider the way forward and that will require new leadership. So today I'm announcing my resignation as leader of the Welsh Liberal Democrats.

In the first Welsh Assembly the Lib Dems formed a coalition with Labour in 2000. The two partiess shared power with Lib Dems members becoming ministers.

The Lib Dems highest number of AMs was six.

Kirsty Williams' statement in full:

I can’t tell you how much of a privilege it has been to serve this party as leader over the last eight years, but with that privilege comes responsibility. Despite our best efforts, and a positive campaign, it has not been enough.
