The Commons authorities have rejected complaints over an event at Westminster involving the Grammy award-winning soul singer Alicia Keys.

The American pop star joined Tottenham Labour MP David Lammy for a lunchtime mini-concert in Portcullis House on Friday which was aimed at raising Westminster's profile among young people especially those from ethnic minorities.

Lammy said he had hoped to introduce young people to the mother of all parliaments while making politicians themselves seem less remote.

"I have been here about 20 months and have to admit there are times I wished parliament was a little bit more modern, a bit more hip, a bit more relevant to people of my generation," the Labour MP said.

The traditionalists at Westminster, or those unused to 21-year-old black female superstars giving concerts in Commons rooms, complained saying the event was a publicity stunt.

The Commons clerk issued a statement on Monday saying the complaints against Lammy would not be pursued.

"The Serjeant at Arms is satisfied by the assurances received from David Lammy that this event, sponsored by the All Party Music group, was not used for commercial purposes," said the clerk.
