Betting firm Paddy Power is to create 500 new jobs in Dublin over the next three years as part of a global expansion.

The company says that by the end of 2013 it will have created an additional 1,440 jobs globally.

Paddy Power will employ over 2,000 staff in Ireland when its expansion here is complete.

The company is also creating 810 jobs in the UK, and 130 jobs in Australia, as its international business grows.

Most of the new Irish jobs will be at its online international business in Tallaght.

The positions are for technicians, quantitative researchers and in marketing and risk management. The rest will be in Paddy Power shops.

The company, which operates in 162 countries, says that growth prospects are strong for its online business. This morning, in an Interim Management Statement, it upgraded its earnings forecast for the financial year.

It says its retail, online and telephone businesses serving Irish customers, which make up about a third of group operating profit, have performed in line with expectations, but that Irish economic conditions have become more challenging during the period.
