LONDON (Reuters) - Bank of England Governor Mark Carney gave a news conference on Thursday after the central bank kept interest rates at a record low once again and trimmed its forecasts for growth in 2017 and 2018 as the impact of Brexit weighed on households' spending power.

Below is a selection of his comments.

ON BREXIT PROJECTIONS

"The MPC's projections continue to be conditioned on a smooth transition to an average of possible outcomes for the UK's post Brexit trading relationships."

"In the MPC forecast, uncertainty about the eventual shape of the UK's economic relationship with the EU weighs on the decisions of businesses and households and pulls down both demand and supply"

ON ECONOMIC GROWTH

"There are encouraging signs that the composition of advanced economy growth is rotating towards investment, supporting the sustainability of the expansion and potentially raising the equilibrium rate of interest."

ON BREXIT UNCERTAINTIES

"It is evident that uncertainties about the eventual relationship are weighing on the decisions of some business. We see it directly in the macro-economic numbers, investment has been weaker than we otherwise would have expected."

ON SMOOTH BREXIT

"As Brexit negotiations proceed, the assumption of a smooth transition into new economic relations with the EU will be tested, if UK households and businesses look through the flurry of headlines, then the economy can be expected to pick up from its current period of sluggishness...

"British related uncertainties are causing some companies to delay decisions about building capacity and entering new markets."
