CONSERVATIVE Bob Blackman ousted Labour's Toby Harris from his Brent and Harrow seat on the London Assembly in one of the most dramatic results of last Thursday's elections.

The former Tory leader on Brent Council polled 34% of the vote against Lord Harris's 30%, with Havard Hughes of the Liberal Democrats third with just under 18%. It was the only GLA constituency seat to change hands, although two top-up seats were gained by UKIP and one by the Liberal Democrats, at the expense of Labour and the Green Party. The Conservatives are now the largest party on the GLA with nine out of 25 seats. The result will also mean that Lord Harris loses his position as chairman of the Metropolitan Police Authority.

In the other elections to take place on Thursday, Ken Livingstone secured a second term as London Mayor with just under 50% of votes cast after second choices were reallocated. In the European elections, both major parties lost ground as UKIP and the Liberal Democrats increased their share of the vote.

Harrow Conservative leader Councillor Chris Mote said: The result shows that the Conservatives are back in business in Harrow. I believe much of this result can be attributed to Labour-run Harrow's high level of council tax and poor service delivery record, and I hope that party takes urgent note of this damning verdict on its administration from the people of Harrow."

But a spokesman for the Harrow's Labour Group played this down, saying: "The Conservative share of the vote in London has fallen by 6% and they have lost two MEPs. The Tories hoped to make a breakthrough in London Mayoral, Assembly and European elections, and they have spectacularly failed in all three."

Harrow Liberal Democrat leader Councillor Paddy Lyne said that she was pleased with her party's performance in all of the elections.
