Lamine Diack, the disgraced former head of athletics' world governing body, has been sentenced by French authorities to four years in prison, two of them suspended, after being found guilty of corruption.

The Senegalese, 87, faced corruption and money-laundering charges linked to the Russian doping scandal.

Diack was convicted of accepting bribes from athletes suspected of doping to cover up test results and letting them continue competing, including in the 2012 London Olympics.

He was also given a maximum fine of 500,000 euros (£456,928).

Diack was investigated by French authorities for four years over claims he took payments of more than 3m euros to cover up cheating.

The judge said his actions had "undermined the values of athletics and the fight against doping".

Diack has been under house arrest in Paris since November 2015.

Previously one of the most influential figures in world sport, Diack was president of the International Association of Athletics' Federations - now World Athletics - for 16 years until he was replaced by Britain's Lord Coe in August 2015.
