Former assistant minister Patrick Kariuki Muiruri has promised to give his rivals a run for their money in the race for Gatundu North parliamentary seat.

He lost the seat to Clement Waibara during the 2007 general election . Muiruri said he used the five years he has been out of politics to build his businesses.

He was speaking at Ngethu shopping centre in the constituency after registering as a voter. Muiruri, who was accompanied by his wife Rachael, said the turnout in the registration in the region is low.

He urged the register so that presidential candidate Uhuru Kenyatta gets wins in the March 4 elections. He said Uhuru will only win if his supporters register and vote for him.

"I am sending a humble appeal to our people to note that Uhuru Kenyatta needs their support to clinch the presidency and they should all turn out in large numbers in all polling stations and register as voters," he said.

Muiruiri will be contesting the Gatundu South seat on the TNA ticket. He called on Uhuru's supporters to vote in TNA MPs to avoid a scenario where the president does not have enough MPs making governance difficult.

He said the entry of DPM Musalia Mudavadi has changed the political scenario adding that he will support the Sabatia MP if he beats Uhuru in the nominations

Mururi captured the seat in 1997 when the constituency was subdivided from the larger Gatundu constituency becoming the constituencies first MP.
