David Cameron becomes the first of the UK party leaders to lend their support to their parties' campaigns for the local elections here in Wales. He'll be visiting businesses in the south of the country before heading north to speak to party activists.

Cameron is expected to deliver a defiant rallying cry when he speaks to activists ahead of local elections next month, the Prime Minister will dismiss mounting criticism and declare ministers are "looking at the horizon not the headlines".

With his leadership under intense scrutiny after a tumultuous fortnight for the coalition - and the Tories in particular - the premier will try to calm nerves ahead of the May 4 ballot box test.

The Prime Minister's visit comes 24 hours after political rivals Labour and the Liberal Democrats deployed high-profile figures to woo Welsh voters.

First Minister of Wales Carwyn Jones spent the day door-knocking in Cardiff, Swansea and Merthyr.

Senior Liberal Democrat Vince Cable visited a blind charity in the Welsh capital before going on a tour of Splott-based steel recycling firm Celsa.
