Lamb has held his current position as chief executive since 1996

Tim Lamb's position as chief executive of the England and Wales Cricket Board is under threat, according to reports.

The Sunday Times claims Lamb faces a vote of no confidence over the ECB's handling of the Zimbabwe crisis and the way it runs cricket in England.

The paper quoted a source as saying: "His position is very precarious and may become untenable in the next few weeks.

"There have simply been too many mistakes on too many issues. We have been wrongfooted on Zimbabwe."

It is understood the chief executives of the 18 first-class counties will this week meet to review the way the ECB has handled the dilemma of England's scheduled tour to Zimbabawe in October.

Lamb and ECB chairman David Morgan meet government officials on Thursday hoping to receive a directive not to tour the troubled country.

But that seems unlikely, meaning England face crippling financial consequences if they boycott the tour on moral grounds.

Lamb's critics believe he should have resolved the Zimbabwe issue months ago, particularly in light of the farcical surroundings of England's 2003 World Cup boycott.

But England remain in a no-win situation and seem set to fulfil the tour despite intense pressure to pull out.

The Sunday Times also claims the counties are unhappy over the complicated issue of domestic reform.

It quotes a county chief executive as saying: "Why does it take six months to ask other people? What is the ECB for?

"It works through committees and goes round in circles. The executive should stand or fall by its decision-making.

"A lot of people are frustrated. If most businesses were run like this, they would not be around."
