House of Lords member Jonathan Marland has became the second British minister to resign in a week amid reports of an upper-house rift within the coalition government.
According to a Downing Street statement on Tuesday, trade minister and former Conservative Party treasurer Lord Marland was stepping down as a minister 'in order to focus on his role in trade promotion.'
The announcement came the day after Thomas Galbraith, known as Lord Strathclyde, quit as Leader of the House of Lords in order to make a return to the private sector.
Marland, 56, will keep his role as Prime Minister David Cameron's Trade Envoy, according to the Daily Telegraph.
Galbraith has admitted that he endured a rocky relationship with Liberal Democrat peers in the Lords, but insisted on Monday that the coalition remained 'remarkably stable.'
Labour vice-chairman Michael Dugher said the resignation proved the government was in 'total chaos.'
'Just one day after their botched relaunch, even people at the very heart of Cameron's government are losing faith and abandoning ship,' he added.
